The Electromagnetic Spectrum All EM waves travel in a vacuum with the speed of light c = 3 10 m/s. The relationship between the speed c, the wavelength , and the frequency f is c = f.
The Ray Model in Geometric Optics A ray is a straight line drawn along the direction of propagation of a wave. A set of light rays can be represented by wave fronts. The rays are perpendicular to the wave fronts at every point in space. Rays and wave fronts for a plane wave propagating to the right are shown in the figure on the left.
Validity of the Ray Model Consider a plane wave incident on a barrier with a circular hole of diameter d The ray approximation assumes
