A particular station of All India Radio,New Delhi, broadcasts on a frequency of 1,368kHz. The wavelength of the electromagnetic radiation emitted by the transmitter is: (speed of light, c= `3.0xx10^8 ms^(-1)`

A

219.2 m

B

2192 m

C

21.92 cm

D

219.3 m

Text Solution

Verified by Experts

The correct Answer is:
D
Frequency v = 1368 kHz
`v=1368xx10^(3)Hz`
`c=3xx10^(8)m//sec`
`lamda=?`
We know that, `v=c/lamda`
`lamda=(3xx10^(8))/(1368xx10^(3))`
`lamda=219.3` metre.
