Calculate the critical angle between diamond (n = 2.42) and quartz (n = 1.46)?

23°
37°
52°
60°

Explanation:

As we know that the critical angle is the angle of incidence at which the light ray will refract at 90 degree angle

so as per law of refraction we will have

here we know that

now we have

so we have

e) none of the above answers are correct

a, c, d, e are all applying about success strategies.
