In Fig. 33-48 a , a light ray in water is incident at angle θ 1 on a boundary with an underlying material, into which some of the light refracts. There are two choices of underlying material. For each, the angle of refraction θ 2 versus the incident angle θ 1 is given in Fig. 33-48 b . The vertical axis scale is set by θ 1 s = 90°. Without calculation, determine whether the index of refraction of (a) material 1 and (b) material 2 is greater or less than the index of water ( n = 1.33). What is the index of refraction of (c) material 1 and (d) material 2? Figure 33-48 Problem 48.

A ray of light is incident through glass, with refractive index 1.52, on an interface separating glass and water with refractive index 1.32. What is the angle of refraction if the angle of incidence of the ray in glass is 25 °?
Light, when incident on a given surface, presents a reflected and a refracted component. When the reflected beam is perpendicular to the refracted beam, the angle of incidence θᵢ is called Brewster's angle. If a beam of light is initially in air with index of refraction n₁ = 1 and is incident on a glass surface (index of refraction n₂ = 1.5), Brewster's angle is:
a)82.9°
b)36.3°
c)75.4°
d)62.9°
e)56.3°
f)45.7°
