A longitudinal progressive wave is given...

A longitudinal progressive wave is given by the equation `y=5x10^(-2)sinpi(400t+x)`. The amplitude and wave length of the wave are (y,x are in m)

A

`A=5x10^(-2)m`, `lambda=2m`

B

`A=5x10^(-2)m`, `lambda=3m`

C

`A=5x10^(-2)m`, `lambda=4m`

D

`A=5x10^(-2)m`, `lambda=5m`

Text Solution

Verified by Experts

The correct Answer is:
A
Comparing with `y=Asin(omegat+kx)`
`A=5xx10^(-2)m`, `K=pim^(-1)implieslambda=(2pi)/(K)`
