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.
