Step 1
In Figure 8, angle Y is the angle of
Answer
The correct answer is B, incidence. Angle Y represents the angle at which the incoming ray of light strikes the surface of the glass block, which is defined as the angle of incidence. This angle is measured between the incident ray and the normal line drawn perpendicular to the surface at the point of incidence.
