NEET Physics Interference MCQ Question
In a double-slit experiment, the path difference between the waves from the two slits at a point on the screen is 3λ. What type of interference occurs at this point?
Constructive interference with maximum intensity
Destructive interference with minimum intensity
Constructive interference with zero intensity
Destructive interference with maximum intensity
Correct Answer
Detailed Explanation
For constructive interference, the path difference must be an integer multiple of the wavelength, nλ. Here, a path difference of 3λ corresponds to constructive interference, resulting in maximum intensity (I = 4I0).
