Concept:
Refraction: The phenomenon of bending of light as it passes obliquely from one transparent medium to another medium is called refraction of light.
When the light rays travel from denser to rarer medium, they bent away from the normal and when the light rays travel from rarer to denser medium, they bent towards the normal.
The point where the incident parallel rays come to a focus after refraction is called the focal point of the lens.
