Red light is incident in air on a 30^o - 60^o - 90 ^o prism as shown. The incident beam is directed at an angle of φ₁ = 47.6^o with respect to the horizontal and enters the prism at a height h = 15 cm above the base. The beam leaves the prism to the air at a distance d = 37.6 cm along the base as shown.

1)

What is φ₂, the angle the beam in the prism makes with the horizontal axis?

degrees

2)

What is n, the index of refraction of the prism for red light?

3)

What is φ₃, the angle the transmitted beam makes with the horizontal axis?

degrees

4)

What is φ_1,max, the maximum value of φ₁ for which the incident beam experiences total internal reflection at the horizontal face of the prism?

degrees

5)

The red beam is now replaced by a violet beam that is incident at the same angle φ₁ and same height h. The prism has an index of refraction n_violet = 1.7 for violet light. Compare d_violet, the exit distance for violet light, to d, the exit distance for red light.

d_violet < d

d_violet = d

d_violet > d

6)

Suppose now that the violet beam is incident at height h, but makes an angle φ_1,v = 60^o with the horizontal. What is φ_3,v, the angle the transmitted beam makes with the horizontal axis?

degrees
