SSM A ray of white light traveling through fused quartz is incident at a quartz–air interface at angle θ 1 . Assume that the index of refraction of quartz is n = 1.456 at the red end of the visible range and n = 1.470 at the blue end. If θ 1 , is (a) 42.00°, (b) 43.10°, and (c) 44.00°. is the refracted light white, white dominated by the red end of the visible range, or while dominated by the blue end of the visible range, or is there no refracted light?

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°
A ray of light enters parallel to the axis of a hollow cylindrical tube. When the tube has only air, the light takes 18.6 ns to travel the full length of the cylinder, but when the tube is filled with a transparent substance, it takes 7.1 ns longer to travel by comparison. What is the refractive incidence of that substance?
A light ray enters the atmosphere of the Earth and descends vertically to the surface a distance h = 100 km below. The index of refraction where the light enters the atmosphere is 1.00, and it increases linearly with distance to have the value n = 1.000 293 at the Earth’s surface. (a) Over what time interval does the light traverse this path? (b) By what percentage is the time interval larger than that required in the absence of the Earth’s atmosphere?
