Question

The penetration of light into the region of geometrical shadow is called(a) Polarisation(b) Interference(c) Diffraction(d) Refraction

Answer 1

Heya Friend,

The penetration of light into the region of geometrical shadow is called Diffraction.

Hence correct option is c). Diffraction.

Hope it helps...

Answer 2

Answer:

c) diffraction.

Explanation:

bending of light around object is called the phenomena of diffraction.

the penetration of light into the region of geometrical shadow it's called diffraction of light.

light actually e does not bend around edges in diffraction but but is able to reach the shadow region due to the emission by the secondary source of light on the edge of the obstacle.
