Question

Assertion (A): In interference and diffraction of light, light energy reduces in one region producing a dark fringe. It increases in another region and produces a bright fringe.
Reason (R): This happens because energy is not conserved in the phenomena of interference and diffraction.

• A. If both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
• B. If both Assertion (A) and Reason (R) are true and Reason (R) is not the correct explanation of Assertion (A).
• C. If Assertion (A) is true and Reason (R) is false.
• D. If both Assertion (A) and Reason (R) are false.

Hint:

In interference and diffraction, energy is redistributed without being lost, preserving conservation of energy.

Answer 1

The Correct Option is C

Explanation of Interference and Diffraction:
- Energy is redistributed, not lost, in interference and diffraction, meaning Reason (R) is false.
- Bright and dark fringes are created due to constructive and destructive interference, respectively.
Thus, Assertion (A) is true, but Reason (R) is false.
