NEET Physics Question (2026) — Solution
Question
In interference and diffraction, the light energy is redistributed. If it reduces in one region, producing a dark fringe, it increases in another region, producing a bright fringe. A. As there is no gain or loss of energy, these phenomena are consistent with the principle of conservation of energy. B. Diffraction and interference are characteristics exhibited only by light waves. Choose the correct answer from the options given below :
Options
- A. A is true and B is also true
- B. A is false, but B is true
- C. A is true, but B is false
- D. Both A and B are false
Answer
C. A is true, but B is false
Step-by-step solution
Statement A is true because interference and diffraction involve the redistribution of energy without any overall loss or gain, which is in accordance with the law of conservation of energy. Statement B is false because interference and diffraction are characteristic properties of all types of waves, including sound waves, water waves, and matter waves, not just light waves. Therefore, Statement A is true, but Statement B is false. Answer: A is true, but B is false
