A certain photon of light has a wavelength of 4.10 x 10-7 m. Calculate the frequency of a photon of this light.

Answer 1

Given:

wavelength = 4.10x10-7 m

Asked for:

frequency

The relationship between wavelength and frequency is the speed of light (c) which is approx. 3x10⁸ m/sec.

The relationship is:

c = wavelength x frequency

Solving for frequency, we have...

frequency = speed of light / wavelength

frequency = 3x10⁸ m/s ÷ 4.10x10^-7 m

frequency = 7.32x10¹⁴ s^-1
