Question

In interference pattern, the energy is

• A. created at the maxima
• B. destroyed at the minima
• C. conserved but redistributed
• D. All of the above

Hint:

Interference follows principle of conservation of energy.

Answer 1

The Correct Option is C

Step 1: Concept:
In interference, energy is neither created nor destroyed. It is redistributed from minima to maxima.
Step 2: Explanation:
Total energy in interference pattern equals sum of energies from individual sources. Bright fringes have more than average energy, dark fringes have less, but total remains constant.
Step 3: Conclusion:
Thus, energy is conserved but redistributed.
