NEET Physics Question - Wave Optics - Young's Double Slit Experiment

Assertion (A): The fringe pattern in Young's double slit experiment is result of both phenomena of interference and diffraction.

Reason (R): Diffraction results from superposition of wavelets of same wavefront.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Assertion (A) is true. The YDSE pattern is an interference pattern modulated by the diffraction pattern from each individual slit.

Reason (R) is true. Diffraction is explained by Huygens' principle, where secondary wavelets from the same wavefront superpose.
Reason (R) defines diffraction but does not explain why both interference and diffraction contribute to the YDSE pattern, so it's not the correct explanation.
