Questions & Step-by-Step Solutions
If two waves of equal amplitude interfere destructively, what is the resultant amplitude?
Step 1: Understand that two waves can interfere with each other.
Step 2: Know that when waves interfere destructively, they cancel each other out.
Step 3: Recognize that 'equal amplitude' means both waves have the same strength or height.
Step 4: When two waves of equal amplitude interfere destructively, they completely cancel each other.
Step 5: Therefore, the resultant amplitude, which is the combined effect of the two waves, is zero.
Destructive Interference – Destructive interference occurs when two waves of equal amplitude are out of phase, resulting in their amplitudes canceling each other out.
Amplitude – Amplitude refers to the maximum extent of a wave's oscillation, and in this case, it is the height of the wave.
