The amplitude of em wave in vacuum is do...

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 the wave propagation chages only

B

The frequency of the wave changes only

C

The wavelength of the wave change only

D

None of the above is true.

Text Solution

Verified by Experts

The correct Answer is:
d
velocity of em wave `c=1/(sqrt(mu_0in_0))`
`=3xx10^8 m//s` is independent of amplitude of e.m.
wave, frequency and wavelength of e.m. wave.
