Study Notes

Geometric Optics

Chapter I studies the fundamental phenomena of geometric optics.

Optical Fibers

The basis for the operation of optical fibers is total internal reflection.

Ray Approximation

In the ray approximation, it is assumed that the wavelength of light is negligible compared to the size of the optical components.
In the ray approximation, the rays of a given wave are assumed to be perpendicular to the wavefront and parallel to the direction of the Poynting vector.

Visual Displays

The phenomenon of refraction and dispersion of light results in visual displays such as the rainbow.
