Math Solution of Geometrical Optics
Math Solution of Geometrical Optics. Light is a form of radiant energy or external cause which creates a sensation of light when enters into our eyes. This radiant energy travels from one place to another place in the form of transverse waves. Light propagates in a straight line in a homogeneous medium. But when the light is incident on a second medium from the first medium some portion of light again causes back in the first medium from the surface of the second in a straight line. This phenomenon is called the reflection of light. Again when light tends to go from one transparent medium to another transparent medium its direction is changed at the surface of separation of the two media. This is known as the refraction of light.
