A `100m` long antenna is mounted on a `500m` tall building. The complex ca become a transmission tower of waves with `lambda`

A

`~400m`

B

`~25m`

C

`~150m`

D

`~2400m`

Text Solution

Verified by Experts

The correct Answer is:
A
Length of the building`(l)=500m`
length of anantenna`(L)=100m`
Wave length of the wave which can be transmitted is `lambda`
as `L~~(L)/(4)implieslambda=4L`
`lambda~~4(100)~~400m`
