A light ray strikes a reflective plane surface at an angle of 65º with the surface. Answer the following questions (show your work)
1) Determine the angle of incidence.
2)Determine the angle made by the incident and reflected rays.

65degrees

130degrees

Explanation:

In reflection, the angle of incidence(i) is the same as the angle of reflection (r)

Given that

Angle of reflection is 65degrees

Hence

i=r = 65degrees

Angle that angle made by the incident and reflected rays = i+r = 65+65

Angle that angle made by the incident and reflected rays = i+r = 130degrees

find the sum of the two horizontal vectors and the sum of the two vertical vectors
