The ratio of amplitude of magnetic field to the amplitude of electric field of an electromagnetic wave propagating in vacuum is
- A inversely proportional to the frequency of the electromagnetic wave
- B the speed of light in vacuum
- C proportional to frequency of the electromagnetic wave
- D reciprocal of speed of light in vacuum
Answer & Solution
Correct Answer
(D) reciprocal of speed of light in vacuum
Step-by-step Solution
Detailed explanation
For an electromagnetic wave propagating in vacuum, the relationship between the amplitude of the electric field \(E_0\) and the amplitude of the magnetic field \(B_0\) is given by the equation \(E_0 = c B_0\), where \(c\) is the speed of light in vacuum. The ratio of the…
