Optics

A lens is a homogeneous transparent medium, such as a glass bounded by two curved surfaces or one curved and one plane surface. This curved surface may be cylindrical, paraboloidal or spherical, but most are spherical. A simple lens is made up of just one transparent element, whereas a compound lens is made up of […]

The world of light is fascinating and confusing. Objects in the mirror appear in different ways because of various phenomena. Reflection works differently for plane mirrors and spherical mirrors.  Two kinds of spherical mirrors are convex and concave mirrors. Mirrors with reflecting surfaces with an inner curvature are concave mirrors, while those with outward curvature

The light we see is always travelling in straight lines. To easily describe its path theoretically, the concept of a ray of light is used to demonstrate the direction and path travelled by light. Light rays reflect off from an object into our eyes, and we see the object via reflection. On the other hand,
