State whether true or false. If false, correct the statement.

The angle of deviation depends on the refractive index of the glass.


Assertion and reasoning type

  1. Assertion: If the refractive index of the medium is high (denser medium) the velocity of the light in that medium will be small
  2. Reason: Refractive index of the medium is inversely proportional to the velocity of the light
