In the figure, light is incident at angle θ1 = 37∘ on a boundary between two transparent materials. Some of the light travels down through the next three layers of transparent materials, while some of it reflects upward and then escapes into the air. If n1 = 1.28 n2 = 1.42, n3 = 1.34 and n4 = 1.47, what is the value of (a)θ5 and (b)θ4? (a) θ5 = Number i Units (b) θ4 = Number Units

$In the figure below, where n1 = 1.94, n2 = 1.57, and n3 = 1.32, light refracts from material 1 into material 2. If it is incident at point A at the critical angle for the interface between materials 2 and 3, what are (a) the angle of refraction at point B and (b) the initial angle θ? If, instead, light is incident at B at the critical angle for the interface between materials 2 and 3, what are (c) the angle of refraction at point A and (d) the initial angle θ? If, instead of all that, light is incident at point A at Brewster's angle for the interface between materials 2 and 3, what are (e) the angle of refraction at point B and (f) the initial angle θ?

Solution

$In the figure, a light ray in air is incident on a flat layer of material 2 that has an index of refraction n2 = 4.4. Beneath material 2 is material 3 with an index of refraction n3. The ray is incident on the air-material 2 interface at the Brewster angle for that interface. The ray of light refracted into material 3 happens to be incident on the material 2-material 3 interface at the Brewster angle for that interface. What is the value of n3? Number Units$
