Critical Angle
What is the critical angle of a
DIAMOND
in degrees?
Hint: The angle of incidence in the denser medium for which the angle of reflection in the rarer medium is 90 degree is called Critical Angle of the denser medium.

The experimental determination of critical angle of diamond is 24.4 degrees.
Critical angle can also be calculated by using refractive index of the material.
where 'n' is the refractive index and 'c' is the critical angle.
