NEET Physics Young's Double Slit MCQ Question
Which of the following statements about Young's double slit experiment is correct?
Interference patterns result from the superposition of light waves from two coherent sources.
The distance between the slits has no effect on the interference pattern observed.
Destructive interference occurs when the path difference is an integer multiple of the wavelength.
The brightness of the fringes is uniform across the entire pattern.
Correct Answer
Detailed Explanation
Statement A is correct as Young's double slit experiment demonstrates how light waves interfere constructively and destructively, leading to observable patterns. Statement B is incorrect because the slit distance does affect the fringe width. Statement C is incorrect; destructive interference occurs at odd multiples of half the wavelength. Statement D is also incorrect as the intensity varies with the position due to the interference pattern.
