(wanna be marked as brainliest then give me the correct answer for this question I repeat give me the correct answer only) the value of amplitude of vibration is approximately 10^-8 or 10 ^-9?
Answers
Answer:
If we vibrate a body a point from the body moves from its equilibrium position. So the maximum distance moved by the point from its equilibrium position is termed as amplitude. It is mainly the one half length of the vibration length. Since vibration waves are formed by vibrating a body, then their amplitude is proportional to the amplitude of the source. The amplitude of vibration is mainly measured in Pascal or Newton per meter square.
We can write the mathematical expression of amplitude of vibration as,
y(x,t)=Asin2π(ft−xλ)
Here, A is the amplitude,
The amplitude of vibration determines the intensity of the wave, which is mainly termed as loudness.
There are two types of wave-transverse wave and longitudinal wave. In case of transverse wave amplitude is the maximum displacement of any point in its string when the string is in equilibrium and in case of longitudinal wave amplitude is the maximum displacement of a particle from its equilibrium position.
So, in case of ordinary conversation between two persons the amplitude of vibration is approximately 10−9 meters.
