Question

When light reflects off a mirror, how are the incident angle of the light, θ i, and the reflected angle of the light, θ r, related?

Answer 1

The incident angle of light, θi, and the reflected angle of light, θr, are related according to the law of reflection, which states that the angle of reflection equals the angle of incidence.

Step-by-step explanation:

The incident angle of light, θi, and the reflected angle of light, θr, are related according to the law of reflection. The law of reflection states that the angle of reflection equals the angle of incidence. In other words, the angle at which the light ray strikes the mirror is equal to the angle at which it reflects off the mirror. This relationship is illustrated in Figure 1.5, where the angles are measured relative to the perpendicular to the surface at the point where the light ray strikes.
