✓✓Dervation of reflection of light through a rectangular glass slab.

$\sf\star\bold\purple{{ANSWER:-}}$

$\sf\implies$ We know that,

• Light travels from rarer to denser medium.

• Light travels from denser to rarer medium.

$\sf\: AT\:FIRST:-$

$\sf\:Incident\:Ray:-$

• Light Ray which travels into a Medium is called Incident Ray.

$\sf\:Reflacted\:Ray:-$

• Light Ray which bends after reflacting is called Reflacted Ray.

$\sf\:Normal\:Ray:-$

• Ray which is perpendicular to Surface at Point of Intersection is called Normal Ray.

$\sf\bold\: CASE\:1$

Refraction when Light Travels from Rarer Medium towards Denser Medium.

$\sf\:EXAMPLE:-$

• When Light travels from Air to Glass (Rarer Medium to Denser Medium).

• It does not move in straight Direction.

• It bends towards the Normal.

$\sf\bold\: CASE\:2$

Refraction when Light Travels from Denser Medium towards Rarer Medium.

$\sf\:EXAMPLE:-$

• When Light Travels from Glass to Air (Denser Medium to Rarer Medium).

• It does not move in straight Direction.

• It bends away from Normal.
