LightAssume a parallel beam of white light strikes a 60 degree equilateral triangular glass prism ( surrounded by air) with n = 1.520 for red light and n = 1.538 for violet. The incident beam strikes one side of the prism at its midpoint with and angle of 60 degrees to the normal surface. The refracted beam then exits some other surface and an arry of color is seen projected on a nearby wall.
a. Draw a ray diagram for both read and violet light that enters the glass and then exits at its first opportunity. Angles should be drawn to scale.
b. What angle are the colors spread out by after they leave the prism?
c. Will total internal reflection prevent the refracted rays from exiting the prism with the above condition? Why or why not?

LightA beam of light enters the gap between two flat vertical and parallel mirrors that are 10 meters tall and are separated by 1 meter. The angle the beam makes to horizontal is 30 degrees. The beam reflects between the two mirrors a number of times before exiting the gap at the top of the mirrors.
a. How many reflections occur before the light beam exits the top?
b. if at every reflections only 95 percent of the light is reflected ( 5 percent is absorbed) what percent of the original beam makes it out the top?
