A glass prism has as principle cross section a triangle ABC
such that ABC= 60°.
A ray SI of red light hits, in air under an angle of incidence of
60°, the face AB of the prism.
The index of refraction of the prism for the incident red light
is n=1.64
1- Study the path of the say SI till it leaves the prism.
2-Determine the value of the angle of incidence of the ray Si so that it would leave the prism grazing it's face AC.

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?
