Index of refraction (n) 1.7 cate flint glass 1.6 Borate flint glass Quartz Silicate crown glass 1.5 Fused quartz Fluorite White lightSilicate flint glass 55.0° 1.4 400 500 600 700 Wavelength in vacuum (nm) Figure 1: Problem 1 Engineering Physics II, workshop Quiz 1, Wednesday March 28th Write your name here: 1. A narrow beam of white light strikes one face of a slab of silicate flint glass. The light is traveling parallel to the two adjoining faces, as shown in the figure in the right For the transmitted light inside the glass, through what angle ?? is the portion of the visible spectrum between 400 nm and 700 nm dispersed? (Consult figure 1 to the right)Explanation / Answer
i = angle of incidence = 90 - 55 = 35
r = angle of refraction
For Voilet :
n = index of refraction of flint glass = 1.663
Using snell's law
1 sin(i) = n sin(r)
sin(35) = 1.663 sin(r)
r = 20.18
for Red :
n = index of refraction of flint glass = 1.622
Using snell's law
1 sin(i) = n sin(r)
sin(35) = 1.622 sin(r)
r = 20.71
difference of angle :-
= 20.71 - 20.18
= 0.53
