The amplitude of em wave in vacuum is doubled with no other changes made to wave. As a result of this doubling of the amplitude, which of the following statement is correct.

A

The speed of wave propagation changes only

B

The frequency of the wave change only

C

The wavelength of the wave changes only

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
Velocity of electromagnetic wave
`c=(1)/(sqrt(mu_(0)epsilon_(0)))=3xx10^(8)"m s"^(-1)`
It is independent of amplitude, frequency and wavelength of electromagnetic wave.
