Question

A ray of light travels through air (n = 1.00) and
approaching the boundary with water (n =
1.33). The angle of incidence is 45.0°.
Determine the angle of refraction.

Answer 1

Answer:

32.1176°

Explanation:

In the picture above, I hope that it's a correct answer.

Answer 2

From the Snell's law, the angle of refraction will be 32.117°.

What is Snell's law?

The Snell's law states that the ratio of sine of angle of incidence and angle of refraction is equal to the ratio of refractive index of second medium to the first medium.

sin i/sin r = n(water) / n(air)

r =sin⁻¹ (sin 45 x 1/ 1.33)

r =32.117°

The angle of refraction is 32.117°.
