Question

A beam of light has a wavelength of 506 nanometers. What is the frequency of the light? What colors is the light?

Answer 1

Beam Light wavelength = 506 nanometer
Frequency of light = F
The color of light = L

To fine the electromagnetic field:
=> S = wavelength x Frequency
Frequency = (3 x 10^8) / (5.06 x 10^ -7)
F = 5.96 x 10^14 Hz

According to the visible light spectrum, wavelength from 495 to 570 is equals to the color of green. Since the given wavelength is 506, thus, the color of light is green.

F = 5.96 x 10^14 Hz
L = green
