Question 7 of 16 Map Sapling Learning macrmilanlaamino You lay a mirror flat on the floor with one edge against a wall and aim a laser at the mirror. The ray reflects from the mirror and strikes the wall. The plane of the incident and reflected rays is perpendicular to the wall. The ray from the laser strikes the mirror 59,7 cm from the wall, and the reflected ray strikes the wall 40.1 cm above the mirror. Find the angle of incidence of the laser ray on the mirror Number 40.1 cm 59.7 cm A O Previous Give Up & View Solution Check Answer Next Ext Hint

Explanation / Answer

angle theta = tan^-1(40.1 / 59.7)

= 34.41 o

angle of reflection = 90 - 34.41 = 55.58o

angle of incidence = angle of reflection = 55.58 o
