Question

question 28 of 28 a mirrors axis runs through the center of the mirror perpendicular to it. what happens when a light ray hits a plane mirror at an angle of 30° to the mirrors axis? a. the ray is refracted at an angle less than 30° to the axis. b. the ray is reflected along a line perpendicular to the mirror. c. the ray is reflected at an angle of 30° to the axis. d. the ray is reflected at an angle of 30° to the mirror.

Explanation:

When a light ray hits a plane mirror, the law of reflection states the angle of incidence equals the angle of reflection, both measured from the mirror's axis (normal). The incident angle here is 30° to the axis, so the reflected angle is also 30° to the axis.

Answer:

C. The ray is reflected at an angle of 30° to the axis.
