Red light has a wavelength of 7 x 10^-7 metres. What is its frequency?
Frequency = Velocity / Wavelength Velocity of light =3 x 10 ^ 8 m/s Your move.
frequency of red light*wavelength of red light = velocity of red light frequency of red light*[7*10^(-7)] = 3*10^8 frequency of red light = (3*10^8)/[7*10^(-7)] frequency of red light = 4.29*10^14
