Problem 2

The reecting surfaces of two mirrors form a vertex with an angle of 120. If a ray of light strikes mirror 1 with an angle of incidence of 55, nd the angle of reection of the ray when it leaves mirror 2.

Step-by-Step Solution:
Step 1 of 3

Modern Physics Lecture 1: Foundations and Special Relativity Position, Time, and Rotation are all continuous symmetries (discrete symmetries such as reflection do not produce the same results as below):  Invariance in position (changing where in space you perform your experiment) proves momentum conservation  Invariance in rotation (eg. rotating your entire experiment by 90 degrees) proves conservation of angular momentum  Invariance in time (changing when in time you perform your experiment, eg. today vs. tomorrow) proves energy conservation Newtonian Mechanics:  Inertia  F=ma  The force of object 1 on object 2 is equal in magnitude to the force of object 2 on object 1  True in an inertial reference frame
