The equation of a stationary wave is
`y=-4sin((pix)/(5)) cos(100pit)`.
Amplitude the progressive wave which produced the stationary wave is

A

1m

B

4m

C

2m

D

8m

Text Solution

Verified by Experts

The correct Answer is:
C
`y=-4sin((pix)/(5)) cos 100pit`
Comparing it with stand equation of stationary wave,
`y=A sin kx.cosomegat`
A=4m
