Question
A sinusoidal electromagnetic wave having a magnetic field of amplitude 1.50 µT and a wavelength of 400 nm is traveling in the +x-direction through empty space. (a) What is the frequency of this wave A sinusoidal electromagnetic wave having a magnetic field of amplitude 1.50 µT and a wavelength of 400 nm is traveling in the +x-direction through empty space. (a) What is the frequency of this wave A sinusoidal electromagnetic wave having a magnetic field of amplitude 1.50 µT and a wavelength of 400 nm is traveling in the +x-direction through empty space. (a) What is the frequency of this waveExplanation / Answer
Accoding to the problem given,
Amplitude (A) = 1.50 * 10-6T
Wave lenght () = 400 * 10-9 m
As from the relation,
f = c/ where f = frequncy and c speed of light = 3 *108m/s
f = c/
f = 3*108/(400 * 10-9)
f = 7.5 * 1015 Hz
