Question

How does the reflection of a wave from an opening change the wave?

a) It increases its frequency
b) It decreases its amplitude
c) It changes its speed
d) It flips its direction

Answer 1

The reflection of a wave from an opening flips its direction without changing its frequency, amplitude, or speed.

Step-by-step explanation:

The reflection of a wave from an opening does not change the wave's frequency, amplitude, or speed. Instead, it flips the direction of the wave. When a wave reflects off an opening or barrier, it changes its direction and travels in the opposite direction from the original wave.
