Question

prove that when a ray of light travels from denser to rarer medium it bends away from the normal​

Answer 1

Answer:

The light ray travel from denser to rarer medium it bend away the normal

To proof : the glass prism travel light it's seem that the light first bend when enter but then it's away and incident ray parallel to emergent ray so u can also seem the case of pencil or a lemon .

this is also because of speed of light in water = 2.25 × 10^8 m/s

and speed of light in air is = 3 x 10^8 m/s
