Question

reflection - part 1
vectored instruction
which line shows how the main beam would reflect?
line number 2
line number 4
line number 3
line number 1

Explanation:

Step1: Understand the law of reflection

The law of reflection states that the angle of incidence is equal to the angle of reflection.

Step2: Analyze each line

• Line 1: Does not follow the law of reflection.
• Line 2: Follows the law of reflection as the angle of incidence (between the main beam and the normal) is equal to the angle of reflection (between line 2 and the normal).
• Line 3: Does not follow the law of reflection.
• Line 4: Is the incident beam, not the reflected beam.

Answer:

Line number 2
