Question

the picture below shows a light ray striking a mirror and bouncing off. use the picture to answer the questions below.
a. what is a called?
b. what is b called?
c. what is c called?
d. if a measures 30 degrees, what is the measurement of c?

Explanation:

Step1: Recall the law of reflection

In the law of reflection, the angle of incidence (angle between the incident ray and the normal) is equal to the angle of reflection (angle between the reflected ray and the normal). Here, angle \( A \) is the angle of incidence, angle \( C \) is the angle of reflection, and line \( B \) is the normal (perpendicular to the mirror surface).

Step2: Apply the law of reflection

Given that angle \( A \) (angle of incidence) measures \( 30^\circ \), by the law of reflection, the angle of reflection (angle \( C \)) is equal to the angle of incidence. So, \( \angle C=\angle A = 30^\circ \).

Answer:

The measurement of \( C \) is \( 30 \) degrees.
