A lens is also known as a Prism because of its refracting surface
Explanation:
- Refractive pattern which occurs in a lens is similar to that which occurs in a Prism.
- In the first surface of the lens there is a refraction of the light due to the change in the refractive index between air and glass.
- The same type of refractive change occurs in a Prism which is made up of glass
- A second refraction takes place in the second surface of the prism similar to that of a lens.
- The deviation of the ray of a light in a lens is similar to that of a Prism.
