What is the amplitude of infrared?
The question is not correctly phrased, Infrared is electromagnetic radiation which consists of waves. Amplitude is a measure of the maximum "strength" or height of the wave and therefore will have a whole range of values from 0 upwards. Infrared does not have a specific range of amplitude however it will have a range of frequencies ( visible light Red end 4 x 1014 Hertz - 3 x 1011 Hertz Microwaves ) and wavelength (visible light Red end 750 nanometres - 1000000 nm nanometres Microwaves)
What are three basic components of all signals?
•Amplitude-Height (loudness) of the wave-Measured in decibels (dB)•Frequency:-Number of waves that pass in a second-Measured in Hertz (cycles/second)-Wavelength, the length of the wave from crest to crest, is related to frequency•Phase:-Refers to the point in each wave cycle at which the wave begins (measured in degrees)-(For example, changing a wave's cycle from crest to trough corresponds to a 180 degree phase shift).
What are three important characteristics of a periodic signal?
Period (or frequency), amplitude and phase. All periodic signals can be broken down into other signals... most commonly sine/cosine waves, but there are others too. These components will each have their own frequency, amplitude and phase that combine into the original signal. The strange part of the question is the phase. A signal on it's own does not have a phase unless you provide some reference signal to compare it to. Generally, this comparison signal is implied by the context of your particular situation. When you decompose a periodic signal into components, however, it is almost always implied that the phase of each component is in reference to the fundamental component (So the fundamental has phase 0, while the others have phases referenced to that). This is done specifically so that each component will combine to create the original signal.
What kind of wave does a microphone make?
A microphone does not generate waves but Rather generates a stream of electrons. Waves needs a medium to propagate like air & water. A broadcasting station does send waves as electrons signals but the medium is not physical
What does a microphone and speaker have in common?
They both convert between electrical impulses and sound waves. The microphone converts sound waves into electrical impulses and the loudspeaker converts electrical impulses into sound waves.
Two waves meet at the same time when one has a instantaneous amplitude of A and the other has the instantaneous amplitude of B Their combined amplitude at this time is?
The amplitudes simply superimpose so it becomes A + B.
How does constructive and destructive interference effect amplitude in waves?
Constructive interference occurs when waves align to increase amplitude, while destructive interference occurs when waves align to decrease amplitude. Constructive interference results in a larger combined amplitude, while destructive interference results in a smaller combined amplitude, or even complete cancellation.
When a combined wave has a lager amplitude that original waves?
When two waves combine to form a new wave with a larger amplitude, it is known as constructive interference. This occurs when the crests and troughs of the waves align, enhancing each other's amplitudes.
What is it called when's. Combined wave has a larger amplitude than the original waves?
That is called reinforcement.
How does the size of a ball on the plunger affect the amplitude of the waves?
The size of the ball on the plunger does not affect the amplitude of the waves. The amplitude of the waves is determined by the energy put into creating the waves and the properties of the medium through which the waves travel. The size of the ball may affect other characteristics of the waves, such as frequency or wavelength, but not the amplitude.
Do constuctive interference waves of the same amplitude cancel each other out?
No, waves of the same amplitude undergoing constructive interference amplify each other, resulting in a wave with a larger amplitude. Waves with opposite amplitudes will cancel each other out through destructive interference.
When waves combine by constructive interference the combined wave has a what?
When waves combine by constructive interference, the combined wave has an amplitude that is the sum of the individual wave amplitudes. This results in a larger, more intense wave.
What wave has the a small amplitude?
A radio wave has a small amplitude compared to other types of waves like sound waves or ocean waves. Radio waves have relatively low energy and long wavelengths, which contribute to their small amplitude.
Two waves that interfere completely result in a wave with a larger amplitude than either of the two initial waves?
This is known as constructive interference, where the peaks and troughs of the waves align to create a stronger wave with a larger amplitude. The two waves are said to be in phase, reinforcing each other to produce a combined wave of greater intensity.
Using the concept of interference explain why the sound levels in the room vary?
The sound levels in the room vary because when its loud the waves combine by constructive interference, the combined wave has a larger amplitude than the original waves did but when its soft the two waves with the same amplitude combine by destructive interference, they cancel each other out.
Is it possible for one wave to cancel another wave and the combined amplitude became zero?
Yes, when two waves meet in opposite phase (one at peak while the other at trough), they can undergo destructive interference which cancels out the amplitudes of the two waves, resulting in a combined amplitude of zero. This effect is commonly seen in physics and can be used to manipulate wave behaviors.
What will happen if waves with same amplitude interact?
If waves with the same amplitude interact constructively, they will combine to create a wave with a larger amplitude. If they interact destructively, they will cancel each other out.
