Question

Given that an electromagnetic wave is generated by an oscillating electron, how are the frequency of the wave and the oscillation frequency of
the electron related?

A. The frequency of the electromagnetic wave is inversely proportional to the oscillation frequency of the electron.

B. The frequency of the electromagnetic wave is equal to the oscillation frequency of the electron

C. The frequency of the electromagnetic wave has no effect on the oscillation frequency of the electron

D. The frequency of the electromagnetic wave is directly proportional to the oscillation frequency of the electron

E. The frequency of the electromagnetic wave is half of the oscillation frequency of the electron

Answer 1

Answer: The frequency of the electromagnetic wave is equal to the oscillation frequency of the electron is the correct option.

Explanation:

Electromagnetic waves are created by oscillating charges. Frequency of waves and oscillation of electron both are the same. Electromagnetic waves are always move perpendicular to the direction in which the wave moves.
