उत्तर

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

Explanation:

  1. Light changes its direction when going from one transparent medium to another transparent medium. This is called the refraction of light.
  2. As every medium has a different refractive index, this causes the direction of light to change.
