Answer 2

$\mathfrak{\underline{\underline{\pink{ <strong><u>Criti</u></strong><strong><u>cal</u></strong><strong><u> </u></strong> \: <strong><u>Angle</u></strong><strong><u>:</u></strong><strong><u>-</u></strong> }}}}$

• The critical angle is the angle of incidence beyond which rays of light passing through a denser medium to the surface of a less dense medium are no longer refracted but totally reflected.

• It is the smallest angle of incidence that yields total reflection.

• The critical angle is the angle of incidence which provides a 90 degree angle of refraction.

• It must be noted here that the critical angle is an angle of incidence value.
