Fill in the blanks and Explain the completed sentences.

a. Refractive index depends on the ............. of light.

b. The change in ................ of light rays while going from one medium to another is called refraction.

Answer :

(a) Refractive index depends on the velocity of light.


Explanation: The velocity of light is different in different medium. Speed of light is more in rarer medium as compared to denser medium. The medium in which speed of light is less, higher is the refractive index of that medium.


(b) The change in direction of light rays while going from one medium to another is called refraction.


Explanation: When a ray of light passes from one medium to another it changes its direction as speed of light is different in different medium. This phenomenon of light is called refraction.
