A beam of light both reflects and refracts at the surface between air and glass as shown in the figure below. If the refractive index of the glass is na, find the angle of incidence 0, in the air that would
result in the reflected ray and the refracted ray being perpendicular to each other. (Use the following as necessary: n.:)

Integrated Tutorial
In a science fiction story, a major character pilots his own spacecraft, which is propelled by a stellar sail. As
shown in the figure (not drawn to scale) a stellar sail is a large reflecting sheet attached to a spacecraft, much
like an ordinary cloth sail is attached to a boat. Light from the star reflects off the sail, exerting a force on the
sail. In the story, the spacecraft is small, and the single passenger sits in a small capsule. The trip is a short
one, and there are no facilities in the capsule for rest, exercise, or nourishment. So we estimate the mass of
the spacecraft, including the passenger and the stellar sail, to be m = 7000 kg. We further estimate the area
of the stellar sail to be A = 8000 m2. Say that the mass of the star is M = 8 M, and its luminosity is
L = 2170 Le, where the subscript o stands for the Sun. The mass of the Sun and its luminosity are
1.99 x 1030 kg and 3.84 x 1026 w, respectively. Find an approximate expression for the net force…

Explain what happens anddeduce an expression for ni in terms of R and d. Consider the refractive index of air to be 1.Note: Remember that all light that falls on a reflecting surface always has part of the light reflected, being refracted or not.refracted or not. Moreover, θc in the figure represents the critical angle at which we have the condition of total internal reflection
