Question

per unit length. Its units are reciprocal of
wavelength unit, i.e.. m'. However commonly
used unit is cm' (not SI unit).
Problem 2.3
The Vividh Bharati station of All India
Radio, Delhi, broadcasts on a frequency
of 1.368 kHz (kilo hertz). Calculate the
wavelength of the electromagnetic
radiation emitted by transmitter. Which
part of the electromagnetic spectrum
does it belong to?
Solution
The wavelength, 1, is equal to c/w, where
c is the speed of electromagnetic radiation
in vacuum and y is the frequency.
Substituting the given values, we have
а с
3.00 x 10ms

1368 kHz
3.00 x 108ms!
1368 x 10's
= 219.3 m
This is a characteristic radiowave
wavelength​

Answer 1

any one use micro waves jsn
