Question

Calculate the frequency of light of wavelength 500nm

Answer 1

Solution: 

The relation of frequency and wavelength is given by v = f λλ 

Given: Speed of light = v = 3 ×× 108 m/s, 

          Wavelength λλ = 500 nm, 

          Frequency f = vλvλ 

                            = 3×108500×10−93×108500×10−9 

                            = 6 ×× 1014 Hz.
