For an electromagnetic wave in free space having an electric field of amplitude E and a magnetic field of amplitude B,the ratio of B/E is equal to A)c. B)c². C)1/c. D)1/c². E) .

Question

Quizplus · Accepted Answer

The value of B/E for an electromagnetic wave in free space is equal to the speed of light, c. This can be derived from the equations that relate the electric and magnetic fields in an electromagnetic wave, which are given by:

E = cB

Taking the ratio of these equations gives:

B/E = 1/c

Therefore, the answer is (C).
