What is Ray Optics?
Ray optics, also known as geometrical optics, is a branch of physics that studies the propagation of light by treating it as a collection of rays. These rays are essentially imaginary lines that represent the direction in which light travels. The form of energy that helps us see the objects around us is called light. The branch of physics that deals with the nature, properties, sources, and effects of light is called optics. Optics is broadly divided into two branches, namely physical optics, which is the study of the wave-like nature of light and the interactions between light and matter.
Ray Optics – Definition, Formula, Applications
Ray Optics is the study of properties of light and optical instruments by assuming that light travels in a straight line. It is also known as geometrical optics, which deals with the geometry of light. Light always travels in a straight line, and the direction in which the light rays propagate is called the ray of light. It studies the principles and laws governing the propagation of light, particularly in the absence of wave effects such as interference and diffraction.
In this article, we will learn about ray optics, reflection, refraction, concave and convex mirrors, lenses, and formulas related to them.
