    In this series, we are going to learn how the phenomenon of refraction of light is best demonstrated using lenses, and what are the real-life applications of these lenses.

    Lens

    When light travels from one optical medium to another, it bends. This phenomenon is called the refraction of light.

    Refraction of Light

    A lens is a transmissive optical device that focuses or disperses a light beam using refraction.

    Types of lenses

    Lenses are classified into two categories: simple lenses and Compound lenses.

    1. Simple lenses
      • Biconvex and biconcave lenses are two examples of simple lenses. They’re also referred

    to as convex and concave lenses.

    Simple Lenses

      • A convex lens refracts the light from a point object in such a way that all the rays converge at a single point after refraction where the image of the point object is formed. As a result, a convex lens is also called a converging lens.
