NEET Physics Interference Assertion Reason Question
Assertion (A): In Young’s double slit experiment all fringes are of equal width. Reason (R): The fringe width depends upon wavelength of light (λ) used, distance of screen from plane of slits (D) and slits separation (d).
Both assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
Both assertion (A) and Reason (R) are true and Reason (R) is NOT the correct explanation of Assertion (A).
Assertion (A) is true and Reason (R) is false.
Assertion (A) is false and Reason (R) is also false.
Correct Answer
Detailed Explanation
The fringe width in Young's experiment is constant for a given setup, and the reason correctly explains the dependence of fringe width on the given parameters.
