Question
What is destructive interference?
Solution
If two waves reach a point in opposite phase, the crest of one wave falls on the trough of second and vice versa. then, the amplitude of the resultant wave is magnitude of scalar difference of the amplitude of two waves.
Thus, the intensity of resultant wave at that point is minimum and destructive interference is said to take place.
Thus, the intensity of resultant wave at that point is minimum and destructive interference is said to take place.
