Option 3 is the correct option to the following question.
Explanation:
Double slit experiment:
The double-slit experiment in modern physics reveals that light and matter can exhibit characteristics of both classically described waves and particles; it also shows the inherently probabilistic existence of quantum mechanical phenomena.
When two wavelength meets ,if the resultant amplitude is maximum then this is known as constructive interference and the resultant amplitude is maximum then this is known as destructive interference.
