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 building complex , `I=100 m , lambda =?`
As , `l=( lambda )/( 4)`
` or lambda=4 l=4 xx 100 =400 m`
