Geometric optics

This course contains 3 segments:

Reflection and refraction

In these videos and articles you'll learn how to determine the angle of reflected light and the definition of specular and diffuse reflection. You'll also learn how to use Snell's law to determine the angle of a refracted light ray. Example problems dealing with the refraction of light rays will be solved. The topics of total internal reflection, critical angle, and dispersion will also be discussed.

Mirrors

Mirrors

In these videos and articles you'll learn how flat and curved/parabolic mirrors create images. The definitions of real and virtual images will be discussed. You'll also learn how to use the mirror equation to determine the image distance, magnification, image height, and object height when dealing with curved mirrors. The sign convention for positive and negative image distance, object distance, and focal length will be discussed.

Lenses

Curved lenses help people see better. In this section you'll learn how to use ray tracings and the thin lens equation to find the location and size of images created by a curved lenses.
