Common questions
What is the Law of Reflection formula?
Law of Reflection is written θᵢ = θᵣ. The angle of incidence equals the angle of reflection, measured from the normal to the surface. It belongs to Optics, under Reflection.
What are the units in θᵢ = θᵣ?
In SI units, \theta_i is angle of incidence, measured in °; \theta_r is angle of reflection, measured in °.
