A sound wave starting from source `S`, follows two paths `SEFD and SEABFD`. If `AB = 1 , AE = BF = 0.6 l ` and wavelength of wave is `lambda = 11 m`. If maximum sound is heard at `D` , then maximum value of length `l` is

A

`11 m`

B

`6 m`

C

`2.5 m`

D

`5 m`

Text Solution

Verified by Experts

The correct Answer is:
D
For maximum path difference `Delta = n lambda`
`2 xx 0.6 l = lambda`
`l = (lambda)/( 1.2) = (6)/(1.2) = 5 m`
