What effect does frequency have on the amplitude of a wave?
Frequency does not have a direct effect on the amplitude of a wave. The amplitude of a wave is determined by the energy of the wave, while frequency refers to the number of wave cycles in a given period of time. Changing the frequency of a wave will not alter its amplitude.
If we wrap a second wire around a guitar string to increase its mass what effect does this have on the frequency and wavelength of the fundamental standing wave formed on that string?
Increasing the mass of the guitar string by wrapping a second wire around it will decrease the frequency of the fundamental standing wave because the wave speed remains constant. The wavelength of the standing wave will be longer due to the decrease in frequency.
How does changing the amplitude change the frequency?
There's no connection between amplitude and frequency. Either one can change, and often does, with absolutely no effect on the other.
How does the Doppler effect alter how we hear sound?
The Doppler effect alters how we hear sound by changing the pitch or frequency of the sound wave when the source of the sound is moving towards or away from us. If the source is approaching, the frequency increases, resulting in a higher pitch; if it is moving away, the frequency decreases, leading to a lower pitch.
What effect does changing the frequency have on light waves?
Changing the frequency of light waves alters their color. Higher frequencies correspond to shorter wavelengths and bluer colors, while lower frequencies correspond to longer wavelengths and redder colors.

The lower the frequency the what the pitch sound?
You're probably think of the Doppler effect, which is the change of the frequency of a signal depending on the motion of the observer relative to the signal source. The typical example involves a car horn and a person standing on the side of the road. If you are standing still next to a stopped car and its horn sounds, you will hear a certain pitch. If the same horn is sounded as the car is driving toward you, the pitch you perceive will be higher - the higher the car speed, the higher the pitch. If the car is driving away from you, the pitch will be lower. This is because the motion of the car is causing the sound waves to compress (driving toward you) or stretch (driving away from you), increasing or decreasing the frequency and raising or lowering the pitch.

Effect of high frequency sounds in birds?

What effect does the amplifier have on the frequency of the signal?
No effect on frequency but increases it's amplitude.
What is the difference between frequency diversity and frequency agility?
Frequency agility is the changing radar frequency rapidly and continuously to minimize jamming effect or enhance the target resolution and hit per scan. where as frequency diversity is a method to couple two radar transmitters to a single antenna simultenously to increase the range of radar in terms of coverage.
Why does observer measure waves from an approaching source as having a higher frequency than if the source were standing?
This is due to the Doppler effect, where the motion of the source compresses the waves as it approaches the observer. This compression increases the frequency perceived by the observer. If the source were stationary, there would be no relative motion and no frequency shift.
What is A change in the observed wavelength or frequency of a wave that occurs when the source of the wave or the observer is moving?
The change in observed wavelength or frequency of a wave caused by the relative motion between the source of the wave and the observer is called the Doppler effect. This effect is commonly observed in situations like the sound of a passing siren changing pitch as it moves towards or away from a listener.
How does photoelectric effect take place below threshold frequency?
It doesn't, and that's the whole big mysterious fact about the photoelectric effect that was standing Physics on its ear about 100 years ago. It doesn't matter how bright the light is, there's no photoelectric effect if the light is below the threshold frequency. And if it's above the threshold frequency, it doesn't matter how dim the light is, those electrons come streaming off of the surface of the target.
