The frequency of the light beam is 4.72 x 10¹⁴ Hz.
Frequency of the light beam
The frequency of light beam and wavelength of light is related in the following equations;
c = fλ
where;
- c is the speed of light = 3 x 10⁸ m/s
- f is the frequency
- λ is the wavelength
f = c/λ
f = (3 x 10⁸) / (636 x 10⁻⁹)
f = 4.72 x 10¹⁴ Hz
Thus, the frequency of the light beam is 4.72 x 10¹⁴ Hz.
