A carrier wave of `2000 kHz` is used to carry the signal, the length of the transmitting antenna will be equal to

A

`3m`

B

`30m`

C

`150m`

D

`3000m`

Text Solution

Verified by Experts

The correct Answer is:
C
Length of antenna `~~lambda`, `v=2000KHz`
here `l=lambda=(C )/(v)=(3xx10^(8))/(2000xx10^(3))=150m`
