What Happens To Sound When The Amplitude Of The Sound Changes?
What happens to sound when the amplitude of the sound changes?
Answer:
When amplitude increases, louder sound will be produced but when amplitude decreases loudness of the sound decreases.
Explanation:
Amplitude is the basis of the loudness of the sound. The higher the amplitude, the louder the sound produced. It is the distance from the equilibrium to the wave crest or wave trough. It will serves as the volume of the sound.
Sound wave
Is an example of longitudinal wave and it travels in a medium. A medium can be gas (air) , solid, liquid. Sound wave travels faster in solid and travel slower in gas medium. Unlike electromagnetic wave (sunlight, radio wave, microwave etc.), sound wave cannot travel in a vacuum like the outer space which means, there will be no sound produced in the outer space. Sound travels slower than light, that is why even if lightning and thunder are made or created at the same time, our eyes were able to observe the lightning first then a couple of seconds we will hear the thunder.
Pitch
Is the highness and lowness of sound. You can hear the sound of motorcycle increases in pitch when you increase or pull the accelerator, and decreases in pitch as you released the accelerator.
Frequency
Is the number of sound waves released by vibration passes a certain point per second. So we can say that frequency is the number of cycles of sound wave per second. The S.I. unit of frequency is Hertz. Frequency can be affected by the length of its wavelength. Long wavelength produces low frequency while short wavelength produces high frequency when both have the same wave speed.
Wavelength
Is the distance from one point of a wave to the same point of another wave. It could be the distance from crest to crest or the distance from trough to trough.
