Question

Consider the case in which light ray A is incident on mirror1, as shown in the figure. The reflected ray is incident on mirror2 and subsequently reflected as ray B. Let the angle of incidence(with respect to the normal) on mirror 1 be A = 37degrees and the point of incidence will be located 20 cm from theedge of contact between the two mirrors. a) What is the angle of the reflection of ray B (with respectto the normal) on mirror 2? Answer in units of degrees. b) Determine the angle between the rays A and B.

Explanation / Answer

When a light ray is reflected the angle is thesame on both side of the reflection for the other side of thenormal is also 37 degrees.  This means that the angle ofthe side x is 90-37=53 degrees. Then allof angles of triangle is 180 so 180-53-90=37 which is theangle of the corner. then the angle of incidencewould be 90-37 which is
53 degrees=B. which is your first answer. Then if you take the ray B and place it at the same spot asray A you will see that they make the same angle and that the anglebetween them is ) degrees.
