A diagram shows a ray of light being reflected by a prism. The critical angle of the prism is 42. Explain if the side xy needs to be silvered like a mirror to cause this reflection.
(The prism is a triangle left corner is a right angle z line to the right is y and above z is x.)
I'm guessing the diagram contains something similar to this?Spoiler:If so, like the diagram indicates, the incident ray will be 45° from the normal, which is bigger than 42°, therefore causing there to be total internal reflection without a silvered surface.Show
I hope this is enough for you to give your own explanation on whether a silvered surface is needed.
