A costume jewelry pendant made of cubic zirconia is submerged in oil. A light ray strikes one face of the zirconia crystal at an angle of incidence of 27°. Once inside, what is the ray's angle with respect to the face of the crystal?

The ray's angle with respect to the face of the crystal is 71.6°

Explanation:

Given that,

Incidence angle = 27°

We need to calculate the angle of refraction

Using Snell's law

Put the value into the formula

We need to calculate the ray's angle with respect to the face of the crystal

Using formula of refraction

Put the value into the formula

Hence, The ray's angle with respect to the face of the crystal is 71.6°
