An EM wave traveling through a vacuum has a frequency of 7.97×1014 Hz. Determine the WAVELENGTH of the wave. Remember, the speed of light is 3×108 m/s. ANS:_________m/wave

Solutions

Expert Solution

Frequency of the EM wave f = 7.97 * 1014 Hz

Speed of the wave                c = 3 * 108m/s

Let the wavelength of the wave be λ

The speed of an EM wave is given by c = f * λ

Then wavelength is given by λ = c/f

                                       = 3 * 108 /7.97 * 1014

                                       = 0.3764 * 10-6 m

                                       = 3764 * 10-10 m/wave
