Two flat mirrors are connected to each other such that they make an angle of . A laser enters the system and first reflects off the bottom mirror, then the top mirror. When the beam exits it makes an angle with respect to the initial beam. What is the expression for the angle between the mirrors ?

Two plane mirrors are facing each other. They are parallel, 3.00 cmapart, and 17.0 cm in length, as the drawing indicates. A laserbeam is directed at the top mirror from the left edge of the bottommirror. What is the smallest angle of incidence with respect to thetop mirror, such that the laser beam (a) hits only one of themirrors and (b) hits each mirror only once?

(b) Number Units No units° (degrees)m

1)Two mirrors make an angle of 128° with each other, as in thefigure. A ray is incident on mirror M1 at an angle of ?inc = 59° tothe normal. Find the angle the ray makes with the normal to M2after it is reflected from both mirrors.
= 69 degrees
2)Repeat the problem if the angle of incidence is 68° and thesecond mirror makes an angle of 108° with the first mirror.
ß = °
