2.
intensity
A tank containing methanol has walls 2.00 cm thick made of glass of refractive index 1.550. Light
from the outside air strikes the glass at a 40° angle with the normal to the glass.
a) Draw the path of the ray and identify angles of incident and refractive ray.
b) Find the angle the light makes with the normal in the methanol. Methanol has a refractive index of
1.329.
c) The tank is emptied and refilled with an unknown liquid. If light incident at the same angle as in part
(b) enters the liquid in the tank at an angle of 20.2. from the normal, what is the refractive index of
the unknown liquid?
