Constructive interference occurs when two waves overlap and the resulting wave has a larger amplitude. Hence, option (2) is correct.
What is interference?
The phenomenon in which there is an overlapping between the two waves propagating in a medium is known as interference. The interference is classified into two categories namely,
- Constructive interference
- Destructive interference
Constructive interference -
It occurs when there is a superposition of the two waves such that the resulting wave has a large amplitude.
Destructive interference -
It occurs when there is a superposition of the two waves such that the resulting wave has a lower amplitude.
Thus, we can conclude that constructive interference occurs when two waves overlap and the resulting wave has a larger amplitude. Hence, option (2) is correct.
