The plane o the incident and reflocted rays is perpar sinkes te w wall. The ray from the laser strikes the mirror 49.3 am from the wall, and the reflected ray strikes the 35.7 cm abóve the mirox. Find the angle of incidence of the laser ray on he mirror r to the Number 35.7 cm 49.3 cm e Prt.fi.is echick Anom. Enli Submd Assgnment F14

Explanation / Answer

Tan(theta) = 35.7/49.3

Theta = 35.9 degree

Angle of incidence = angle of reflection

Angle of incidence (theta I) = 90-35.9 = 59.1 degree
