<ul>
<li>A straight line that originates at some point is called a ray.</li>
<li>The part of optics dealing with the ray aspect of light is called geometric optics.</li>
<li>Light can travel in three ways from a source to another location: (1) directly from the source through empty space; (2) through various media; (3) after being reflected from a mirror.</li>

Summarizing the Ray Aspect of Light

Physics is a science discipline concerned with the nature and properties of matter and energy. Physics topics include mechanics, heat, light and radiation, sound, electricity, magnetism, the structure of atoms, and so on.

Physics

Explore the principles of light and its behavior, including reflection, refraction, total internal reflection and dispersion, leading to an understanding of image formation by lenses and mirrors in this tutorial.
