What happens when two waves undergo destructive interference?
A
They cancel each other out completely
B
They combine to form a wave with reduced amplitude
C
They combine to form a wave with increased amplitude
D
They combine to form a wave with a different frequency
correct option: a
Explanation: Destructive interference occurs when two waves are out of phase, meaning their crests and troughs are misaligned. In this case, the amplitudes of the waves subtract from each other, resulting in a wave with reduced or zero amplitude at certain points.
