Question

which line shows how the main beam would reflect? line number 2 line number 1 line number 3 line number 4

Explanation:

Step1: Recall the law of reflection

The law of reflection states that the angle of incidence is equal to the angle of reflection. The angle of incidence is the angle between the incident ray (main beam) and the normal (line 3). The angle of reflection should be equal to this angle and on the opposite side of the normal.

Step2: Analyze each line

• Line 1: Does not follow the law of reflection as the angle with the normal is not equal to the angle of incidence.
• Line 2: Follows the law of reflection as the angle with the normal is equal to the angle of incidence of the main beam with the normal.
• Line 3: Is the normal, not the reflected ray.
• Line 4: Does not follow the law of reflection as the angle with the normal is not equal to the angle of incidence.

Answer:

Line number 2
