Question

A wave that reflects off a fixed boundary, will have: (Check all that apply)

A. the same orientation
B. the same frequency
C. the same amplitude
D. the opposite orientation

Answer 1

When a wave reflects off a fixed boundary, it has the same frequency and opposite orientation, while the amplitude remains the same. Hence the correct answer is option B and D

Step-by-step explanation:

The reflection of a wave off a fixed boundary involves several changes. The amplitude of the reflected wave remains the same as the amplitude of the incident wave, resulting in the same amplitude. However, the reflected wave is inverted and reflected 180 degrees out of phase with the incident wave, meaning it has the opposite orientation. The frequency of the reflected wave remains the same as the frequency of the incident wave.

Hence the correct answer is option B and D
