Waves Vibrations and Oscillations

Parent Category: Mechanics
From pendulums, to sound, to Schrödinger's equation, waves and vibrational motion are of fundamental importance to all of the disciplines of physics. Please direct all questions concerning the causes, mechanics, applications, and significance of oscillatory behavior into this category.
A: actually any active components will oscillate with positive feedback A transistor can be used as an amplifier along with an LC tank circuit to form an oscillator; it is an active device (as LIBURNO states) which will amplify the feedback signal coming out of the LC tank circuit. The tank circuit...

Data representation. Cumulative frequency is the sum of all previous frequencies.
A local oscillator can be a crystal oscillator.
The resistor allows a slow charge to enter the capacitor. When this charge reaches a certain point the circuit activates and forces the capacitor to discharge. Once discharged the circuit reverses itself and starts the charge over again. The larger the cap and/or resistor the lower the frequency...
The wavelength of light times the frequency of light is its speed, which is close to 2.9979*10 8 m/s in most mediums.
Simple harmonic motion is understood from an oscillating pendulum.It is also periodic. An example of periodic motion without simpleharmonic motion is the rotation of the blades of a fan.
All radio (and TV and GPS and cell-phones [all of which are really radios]) work by transmitting and/or receiving electromagnetic waves.
A simple pendulum has one piece that swings. A complex pendulum hasat least two swinging parts, attached end to end. A simple pendulumis extremely predictable, while a complex pendulum is virtuallyimpossible to accurately predict.
I have no video but electromagnetic wave may harm and may not It is divided to seven the radiowaves,microwave,infrared,visible light,ultraviolet light,X-rays,andlastly Gamma rays. The waves that is not harmful is from radio waveto visible light then the rest may harm
v=fλ Visible light is an electromagnetic wave. All electromagnetic waves travel at 3.0x10 8 m s -1 in a vacuum. Since the question doesn't supply additional info I'm assuming the medium is a vacuum. Hence, v=3.0x10 8 m s -1 and λ=486x10 -9 m. Therefore, f=v/λ = 6.17x10 14 Hz
Sound wave travels from one part in to another part in air due tochange in density of molecules from one point to another point
The total of all electromagnetic waves is called theelectromagnetic spectrum. . The electromagnetic spectrum includes radio waves, microwaves,infrared radiation, visible light waves, ultraviolet radiation,x-rays, and gamma rays. Only visible light waves, which humans seeas the band of colors from...
No. Otherwise it is no standing wave.
Frequency of em radiation is inversely proportional to its wavelength.so, frequency increases with decrease in wavelength.
The math that describes them, Fourier transforms allow one to add wave functions. Also thr fact that they are waves so wave adding together or "cancelling " each other out is possible, wave interference both constructive and destructive does occur.
They transport energy . They have amplitude . They have frequency . They can be measured i m not use to yor acount , so pls delete acount pls
RC phase shift oscillators are used for musical instruments, oscillators, voice synthesis, and GPS units. They work at all audio frequencies.
A: Very easy to do just provide a positive feedback and/or a phase shift it will oscillate
It will become longer, and it will carry less energy, its alsolikely, that if the change or loss in frequency is enough, theradiation will become a different type of electromagnetic radiationin the spectrum like gamma to x-rays or visible light to infraredand so on.
wavelength. The larger the frequency, the smaller the wavelength.
Frequency is inversely proportional to wavelength (higher frequency means a shorter wavelength). Frequency is directly proportional to the energy of the wave (higher frequencies correspond to higher energies).
V=f *lambda where v = wave speed, f=frequency and lambda=wavelength. . Frequency increase as the energy of a wave increases becauseE=hf where h is a constant so E/h=f. if E increase f has toincrease. . Wavelength decreases because if the frequency increases thewavelength would also have to decrease...
Longitudinal waves require a medium to propogate . Example aresound waves
Though it is not possible to get a mathematically perfect square wave from a sine wave, it is possible to get a reasonably close square wave from a sine wave. A clipper circuit is one which clips off the top of a sine wave thus giving it a flat top. Clipper circuits find their applications in...
An increase in atmospheric __o[ ___ leads to an increase in the greenhouse effect
A mechanical wave is a disturbance (an oscillation) that movesthrough a medium. The source transfers mechanical energy into themedium itself, and the medium propagates the energy of the wave.Examples are sound and an earthquake, and a tsunami. == A mechanical wave is a disturbance that travels...
Yes, The speed of sound in dry air is approximated by the equation: v = (331 + 0.6*T) m/s where T = temperature in degrees Celsius
Anything in the electromagnetic spectrum. Gamma rays Xrays Ultraviolet Visible Light Infra-red Microwaves Radio Waves They are characterised by the fact they are all transmitted in packets of energy called photons. Sound is not an electromagnetic wave, nor is ultrasound or any physical...
The type of wave the kink in a lasso travels as is a " longitudianl wave ".
The high point on a sound waveform is the point of maximum pressure, the pressure peak.
everyone that is still alive??
Wavelength x amplitude = speed of the wave.
Well, its got you looking at a computer screen, but I prefer to point to TV and smart phones as examples of "effecting". =========================== Answer #2 (from another contributor): Personally, I very much appreciate the electromagnetic waves in the thermal and visible bands,...
Amplitude. An increase in this property will result in an increase in volume of the sound.
Frequency. Electromagnetic waves are just magnetic waves that are turning into electric waves. The faster they turn in to each other, the more energy and high up on the spectrum they are.
P waves are the least damaging and only travel left and right, forward and backward along the horizontal plane. S waves are the most dangerous because they cause up and down motion and travel along the surface and solids of a medium causing the most destructive force. However they do not travel as...
The frequency of an EM wave is inversely proportional to its wavelength, which can be seen in the equation f=v/ λ, where f is the frequency, and λ is the wavelength.
The period of a 15MHz sine wave is 1 / 15MHz, or 0.066667 us, or 66 2 / 3 ns.
Possibly could use a wheel alignment, or tire pressure on all tires the same,or it also could be your stabilizer rods need replacing and while your looking at them check your struts and springs.good luck with that.
Approximately 10 to the power of minus 7 Metre, which is 1/10,000,000th of a Metre
There frequency is inversely proportional to there wave length. There energy level go on reducing as there frequency decreases.
Because waves only move energy, not material. If they're mechanicalwaves, then the material along their path just wiggles but doesn't movefrom one place to another. So there's nothing to blow in your face. Certainly, the sound wave causes increased pressure against yourface. But it does that...
The wavelength of a wave would double if the frequency was cut in half. Wavelength=c/frequency where c equals the speed of light.
Resonance at sub synchronous speeds or frequencies. Generators designed to run at 60 Hz may have a sub synchronous resonance at 20 Hz, for example. If run at a resonant frequency, the resonance can cause increasing vibrations that will eventually do very bad things (things will start to break).
The frequency and wavelength are the same thing. Not effected by the amplitude in the least.
Heat can travel in 3 ways: conduction, convection, and radiation. If the air or fluid are sufficiently transparent and the difference in temperatures big enough, radiation can be a significant mode of heat transfer. Because gases and liquids can move around, natural convection and forced...
Solar waves are waves that wave solarly.
Isaac newton(england), while sitting on a church bench
When external periodic frequency matches with any of the Naturalfrequency of a body , the body vibrates with larger amplitude .This phenomenon is known as Resonance
Light is a form of radiation. Light waves are a part of the electromagnetic spectrum, and they do not require a medium to travel. You can think of light as both a wave and a particle (photons). Sound waves are compressions of matter. They travel through gas, solids, and liquids, but not through...
When the observer is moving relative to the wave source, the observer experiences the Doppler Effect. The motion of the source causes a change in the sound's wavelength. Wavelength is inversely proportional to frequency. The apparent frequency is given by the equation: f = (v- v r )/(v- v s ) ...
A good example is SO2 molecule. The Lewis structure shows 1 O single bonded to the S atom and the other O double bonded to the S atom. A double bond is shorter than a single bond. But when the bond length is measured by microwave absorption, the bonds were idenical. I say the pair of electrons that...

Magnification, such as in lenses: eyeglasses, telescopes,microscopes. Raindrops refract different wavelengths of light atdifferent angles, to produce rainbows.
describes the effect of water waves passing into shallow water?
whether you are talking about waves on the beach or waves of light or sound waves. the time it takes for one wave to oscillate completely is the period of the wave. if, however you would like to know how many oscillations each wave completes per second, then you would be looking for frequencys
If the pendulum is light it will be susceptible to perturbations from air currents, leading to a loss of accuracy.
Reflection A wave that bounces off an object is a reflected wave.
It is a very vague question, so i will throw some equations at you: For relating energy of photon to the frequency: E = hf = hc/L h = planck's constant = 6.63 X 10^-34 f = frequency of wave (Hz) L = wavelength (metres) For relating luminosity (power) to surface area and temperature: Luminosity =...
From largest to smallest wavelength, the spectrum follows this order: Radio Microwave Infrared Visible Ultraviolet X-ray Gamma ray
it is longitudinal waves. for a+ users.
If the frequency decreases, then the wavelength increases - assuming the speed of the wave doesn't change. In general, the product of the frequency and the wavelength is equal to the wave's speed. If the frequency decreases, then the wavelength increases - assuming the speed of the wave doesn't...
By convention, that's said to be the direction of the E field.
The wave you are referring to could be a Mexican wave. A wave is produced when particles of the medium(eg.air) move back and forth. This movement moves other objects back and forth. Therefore there is a succession of vibrations, which is called a wave. A group in the wave will be 'compressed' or...
Electromagnetic waves are not produced, they exsist as part of the electromagnetic force (one of the four knows forces, like gravity), science still does not have an answer to how the four knows forces first began, this is one of the reasons for the large hadron collider, to try and find out how the...
Light waves are transverse electromagnetic waves.
When electric charges are at rest then only electric field exists around that stationary charge. When the charge is in uniform motion, then apart from electric field a magnetic field is also produced. But when the charge is accelerated then it produces a disturbance even in the free space ie vacuum....
The greater the frequency, the greater the pitch. The greater the amplitude, the greater the volume.
Hertz are used to measure cycles per second. Sound is measured in hertz. I hope I understood the question.
The angle of incidence of a light ray = the angle of reflection. Also, when light is incident on a medium of higher density than the current medium (e.g. a glass mirror in air) then the wave undergoes a 180 degree phase shift. If the surface is rough and bumpy, then the rays are scattered about all...
that they are caused by processes similar to those that create earthquakes.
Radio waves answ2 . Radio waves down to about 10kHz are used to communicate with submarines, without their surfacing. Your national power grid radiates E-M waves at its operating frequency, but not intentionally. Lightning strokes radiate over a wide spectrum, even into the low audio range,...
At resonant frequency, current in the circuit is maximum.Impedenceis minimum.
1. Mass distruction to natural and human made materials.
Constructive interference occurs when waves meet at point in the medium in phase or having phase difference as integral multiples of 2pi
All electromagnetic waves move at the speed of light (c = 3.00x10 8 m/s). Using the relationship that the speed of a wave is equal to the product of wavelength and frequency (v = lambda*f), we find that for an electromagnetic wave: c = lambda*f. That is, for an electromagnetic wave, the wavelength...
The product of (wavelength) times (frequency) is equal to the speed of the wave.
Double refraction is when you can see through a mineral and it shows two images instead of one. Calite is the mineral that exhibits it. I linked a great website for this kind of stuff below.
The vibrations caused by an earthquake are known as seismic waves. These can be split into two types, surface and body waves. Surface waves travel only through the crust and there are two main types: . Rayleigh waves . Love waves These surface waves tend to be the most damaging and are...
