The law of reflection is quite useful for mirrors and other flat,shiny surfaces. (This sort of reflection is called specularreflection). However, you've likely been told that when you look atsomething, you are seeing light reflected from the object that youare looking at. This is reflection of a different sort: diffusereflection. In this problem, you will see how diffuse reflectionactually arises from the same law of reflection that you areaccustomed to for reflections from mirrors.

Suppose that the spotlight shines so that different parts of thebeam reflect off of different two surfaces, one inclined at anangle alpha (from the horizontal) and one inclined at an anglebeta. What would the angular separation \Delta \theta be betweenthe rays reflected from the two surfaces? Assume that the lightcomes at an angle theta_a to the vertical.
Express your answer in terms of some or all of the angles theta_a,alpha, and beta.

(a) What would be the angle of reflection for an angle of incidence of 32°? (b) What would be the angle of incidence for an angle of reflection of 47°? (c) What would the angle of reflection be If the incident ray was 40° from the reflecting mirror surface?
