(1) Building contractors often install double-glazed windows to prevent thermal energy (heat) from entering or exiting a building. In addition to being effective insulators, such windows present interesting optical effects.
In the figure, a double-glazed window consists of two identical panes of glass (ng=1.40), each yg=52.0 mm thick, separated by an air gap of ya=41.6 mm . If light incident on the glass makes an angle of ϕ=40.00∘ with respect to the glass, find the shift in path Δx as the light enters the room. Use na=1.00 for the index of refraction of air.
(2) The index of refraction of silicate flint glass for red light is 1.620 and for violet light is 1.660 . A beam of white light in this glass strikes the glass–air interface at a 25.10° angle of incidence and refracts out into the air. What is the angular separation between the red and violet components of the spectrum that emerges from the glass?
1)
Using Snell's law,
n1 sin(i) = n2 sin(r)
1 sin(50) = 1.40 sin(r1)
r1 = 33.17°
Shift, L1 = 52 sin(50 - 33.17)/cos(31.17) = 17.59 mm
For glass 2,
1 sin(50) = 1.40 sin(r2)
r2 = 33.17°
Shift, L2 = 52 sin(50 - 33.17)/cos(31.17) = 17.59 mm
Shift, L = L1 + L2 = 35.19 mm
