Reflection of Light: The phenomenon of bouncing back of light into the same medium by the smooth surface is called reflection.

Refraction of Light: The bending of light at the interface of two different mediums is called the Refraction of light.

  • If the velocity of light in a medium is more, then the medium is called optical rarer.
    For Example, air or vacuum is more optical rarer.
  • If the velocity of light in medium is less, then medium is called optical denser.
    Example, glass is more denser than air.
