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

`~400m`

B

`~25m`

C

`~ 150 m`

D

`~ 2400 m `

Text Solution

Verified by Experts

The correct Answer is:
A
Given, length of the building (l) is given by l = 500 m
We know that, wavelength of the wave which can be transmitted by `lamda =4l = 4xx100 = 400 m`.
