Answer 2

Answer:

I think this answer is enough you

Explanation:

When an oblique ray of light travels from optically denser medium to an optically rarer medium, it bends away from the normal at the surface separating the two media.

∙ According to Snells law, the angle of refraction increases with the increase in the angle of incidence. The figure below shows refraction between two media.

∙ As shown in the figure above, the rays AB

and AB

originating from Point A of the source undergoes partial refraction and partial reflection.

∙ The refracted ray for the incident ray AB

travels along the surface separating the two media. So, its angle of refraction is 90

∘

.

∙ When a ray of light travels from the denser medium to the rarer medium, the angle of incidence for which the angle of refraction is 90

∘

is known as the critical angle.

∙ When the angle of incidence exceeds the critical angle, the ray is totally internally reflected. This is the phenomenon of total internal reflection.
