Visible light is just a small part of the electromagnetic spectrum. In a vacuum, all electromagnetic particles travel at the same speed, c, which is 3.00 x 108 m/s.

The wavelength of an electromagnetic wave which has a frequency of f is given by the equation λ = c / f.  λ is the Greek letter lambda, and represents the wavelength.

From the equation, it is evident that electromagnetic waves with a larger wavelength have a
