Question

Assertion (A): The refractive index of diamond is V6 and refractive index of a liquid is 13. If the light travels from diamond to the liquid, it will be initially reflected when the angle of incidence is 30°. 1 Reason (R): where u is the refractive sin' index of diamond with respect to liquid.​

Now, we know that critical angle is given by,

C=sin
