Question 9: EM waves

Question

The ratio of amplitude of magnetic field to the amplitude of electric field of an electromagnetic wave propagating in vacuum is

Accepted Answer

For an electromagnetic wave, Speed of electromagnetic wave, $$c=\frac{E_0}{B_0}$$
$$	herefore \frac{B_0}{E_0}=\frac{1}{c}=$$ reciprocal of speed

Answer

reciprocal of speed of light in vacuum

Answer

the speed of light in vacuum

Answer

proportional to frequency of the electromagnetic wave

Answer

inversely proportional to the frequency of the electromagnetic wave

EM waves
