Answer : Destructive interference = cancellation
Explanation :
When two light waves superimpose on each other, the light gets distributed. This phenomenon is known as the interference of light. The condition for the interference is that there should be a zero phase difference between two waves.
There are two conditions for the interference of the light:
- Constructive interference
- Destructive interference
Another name of destructive interference is cancellation. This is due to the reason that the amplitude of both waves in these type gets canceled and the intensity of the light decreases.
Hence, the correct option is (A).
