A `100 m` long anteena is mounted on a `500 m` tall building. The complex can become a transmission tower for waves with `lambda`.

A

`~ 400 m`

B

`~ 25 m`

C

`~ 150 m`

D

` ~ 2400 m`

Text Solution

Verified by Experts

The correct Answer is:
A
For given buildings complex , ` l = 100 m , lambda = ?`
As ` l = ( lambda)/(4) or lambda = 4 l = 4 xx 100 = 400 m`. Thus option (a) is correct.
