Are oceanic plates measured in seismic waves?

No, oceanic plates are not measured directly in seismic waves. Seismic waves are used to study the behavior of tectonic plates, including oceanic plates, by analyzing how they interact with each other and the Earth's interior. Measurements of oceanic plates involve techniques like satellite mapping, bathymetry, and GPS data to track their movement and deformation.

Disadvantages of electromagnetic waves?

Electromagnetic waves can cause health hazards like cancer and genetic mutations with long-term exposure. They can also interfere with electronic devices and sensitive equipment. Additionally, some electromagnetic waves, such as ultraviolet and X-rays, can cause harm to living tissues.

What are dispersion bonds?

Dispersion bonds are chemical bonds that occur in certain crystal structures where electrons are delocalized, leading to unique optical and electronic properties. These bonds are important for materials science, particularly in the field of semiconductors and optoelectronics.

Does resonance occur in the middle ear?

Resonance occurs in the outer ear and is a function of the length of the auditory canal, wherein some frequencies are enhanced by combinatorial properties of other incoming frequencies - the frequency reinforced the most is termed the 'resonant frequency' of the canal.

Is electromagnet and electromagnetic waves are the same?

No, an electromagnet is a device that produces a magnetic field when an electric current flows through it. Electromagnetic waves, on the other hand, are a form of energy that includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays, produced by the oscillation of electric and magnetic fields.

Are primary seismic waves slower than secondary waves?

Primary waves are called so because they are the first to arrive, and secondary waves are called so because they arrive second. Based on this logic I would say no. There is in fact a marked difference, which is used to tell how far away the epicenter is from a particular seismograph.

How can a electromagnetic wave transmit location?

Direction finding depends on a process of triangulation. Ship's navigators used to do this by sighting three points on the shore and plotting the angles on a chart. Then this method was adapted by using radio transmitters, and with a receiver that has a sharply defined angle of acceptance, you can do the same thing. Nowadays with satellites the system of GPS (Global Positioning System) has evolved. The receiver detects the angles of three satellites and works out the position automatically.

In a horizontal finger wave waves are positioned sideways and?

create an "S" shape along the hair, styled close to the scalp for a classic and elegant look. This vintage hairstyle was popular in the 1920s and 1930s, often seen in glamorous Hollywood films of the time. It requires careful styling and setting the waves with hairpins and setting lotion for a smooth and defined finish.

How many resonance structures does the oxalate ion have?

There are 50 electrons in a sulphate ion.

16 in the sulfur base 8 in each of the 4 oxygen and 2 for the negative charge

this equals 50

What are the highest points on a standing wave called?

When the trough of a wave and the crest of a different wave meet, the waves cancel completely. This is called destructive interference.

What kind of seismic sea wave can cause great devastation?

A tsunami, which is typically triggered by underwater earthquakes, volcanic eruptions, or landslides, can cause great devastation. Tsunamis travel at high speeds across the ocean and can create massive waves when they reach the coast, causing widespread destruction and loss of life.

What is the definition of electromagnetic wave?

An electromagnetic wave is a type of energy wave that consists of vibrating electric and magnetic fields propagating through space. These waves carry energy and information through a vacuum or a medium, and they travel at the speed of light. Examples of electromagnetic waves include radio waves, microwaves, visible light, X-rays, and gamma rays.

Is the motion of the celling fan a periodic motion?

if a motion repeats it self after equal intervals of time it is called a periodic motion, if u understand this definition u will know that a fan is undergoing the periodic motion as if of its blades in proper words the blades of an electric fan is a periodic motion

What are the two types of body waves and what do they mean?

The two types of body waves are longitudinal and transverse waves. In seismology longitudinal waves are known as P-waves (P = primary as they are detected by seismometers before the other seismic waves) and transverse waves are known as S-waves (S = secondary).

In longitudinal waves the material oscillates or moves backwards and forwards parallel to the direction of wave motion (a bit like someone opening and closing an accordion). In transverse waves, the material oscillates normal (at 90 degrees) to the direction of wave motion.

Are seismic waves transverse or compressional waves?

Seismic waves can be either transverse or compressional. P-waves are compressional waves that travel fastest, while S-waves are transverse waves that travel slower. Both types of waves are generated by earthquakes and used to study the Earth's interior.

What are waves in the open ocean called?

Waves in the open ocean are called ocean waves. These waves are generated by the wind and can travel vast distances across the ocean. Ocean waves can vary in size and strength depending on factors like wind speed and duration.

Are slow waves higher in pitch than fast waves?

Not necessarily. The frequency of a wave is equal to the speed divided by the wavelength so if it is fast and has a low wavelength then it will be high pitched. If it has a very large wavelength though it will have a lower pitch.

How do you Calculate the frequency of this wave lengths of electromagnetic radiation?

To calculate the frequency of electromagnetic radiation, you can use the formula: frequency (f) = speed of light (c) / wavelength (λ). The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second. Plugging in the wavelength in meters will give you the frequency in hertz (Hz).

Why are resonance structures used to model certain molecules?

Resonance structures are used to model certain molecules because they provide a more accurate representation of the electron distribution in the molecule. The actual structure of the molecule is often a hybrid of the different resonance structures, which helps to explain the stability and reactivity of the molecule. Resonance structures are particularly useful for molecules with delocalized electron systems, such as aromatics or carbon-carbon double bonds.

How is a seismic wave sensed?

seismic waves are sensed with these special technology monitors that have the power of bats . bats cant see but when there going towards something they feel vibrations then they know were there going

Which of these kinds of electromagnetic waves has the lowest frequency x-rays infrared light ultraviolet light blue light or yellow light?

Yellow light has the lowest frequency among the electromagnetic waves listed. The frequency of electromagnetic waves increases from radio waves to gamma rays, with yellow light falling in the visible light spectrum.

What is ZVS quasisquare-wave converter?

ZVS techniques are techniques that force the voltage across a switch to be zero just

before it is turned on or off and to keep this voltage zero while a switching transition

occurs. All MOSFETs and most IGBTs have anti-parallel diodes that are built into the

body of each device that allows current to flow from source to drain in a MOSFET and

from emitter to collector in an IGBT. A ZVS turn-on in MOSFETs and IGBTs is

therefore done by forcing current through the body-diode of the devices just before they

are turned on. This clamps the voltage across the device to a single diode drop (which is a

negligible voltage) during a switching transition so that turn-on switching losses are

greatly reduced. A ZVS turn-off is achieved by slowing down the rate of voltage rise

across a switch when it is turned off by adding some capacitance across the switch; this

limits the overlap between voltage and current during the switching transition

What is an example of seismic waves?

an example of a seismic wave would have to be when you are recording your voice, sound waves come out of your mouth and you can see the line that moves up and down to the tone of your voice like triangles without a bottom varying in size.

What is the Difference between sound power level and sound pressure level?

Sound power or sound intensity I is a sound energy quantity.

Sound pressure p is a sound field quantity.

Sound intensity is sound pressure squared. I = p².
