The stationary wave produced in a stretc...

The stationary wave produced in a stretched string is given by `Y=A Cos ((2pix)/lambda) sin ((2pit)/T)`
The corresponding progresing wave has an amplitude equal to

A

A/2

B

A

C

2A

D

`A//sqrt2`

Text Solution

Verified by Experts

The correct Answer is:
A
On account of super position the amplitudes get added . Since the two waves travelling in opposite directions are sinuites they produced maximum displacement equal to twice the amplitude of either
