A stretched string of length l, fixed at both ends can sustain stationary waves of wavelength `lambda` given by

A

`lambda=(l^(2))/(2p)`

B

`lambda=(p^(2))/(2l)`

C

`lambda=2lp`

D

`lambda=(2l)/(p)`

Text Solution

Verified by Experts

The correct Answer is:
D
`l=l_(1)+l_(2)implies(1)/(n)=(1)/(n_(1))+(1)/(n_(2))( :. lalpha(1)/(n))`
