उत्तर

Light changes its direction when going from one transparent medium to another transparent medium. This is called refraction of light.

Explanation:

  • When light travels through a transparent material, like glass or water, it bends, a phenomenon known as refraction.
  • This occurs because light travels at various speeds through different optical densities.
