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 :
Interference and Diffraction: Energy Redistribution
The question concerns the redistribution of energy in light during interference and diffraction phenomena.
Statement A Analysis: Conservation of Energy
Interference and diffraction patterns are formed by the superposition of waves. In these patterns, energy is redistributed. Bright fringes represent regions where constructive interference concentrates energy, while dark fringes represent regions where destructive interference minimizes energy. This redistribution does not create or destroy energy; the total energy remains constant across the entire pattern. Therefore, these phenomena are consistent with the principle of conservation of energy.
Conclusion: Statement A is true.
Statement B Analysis: Wave Characteristics
Interference and diffraction are fundamental characteristics of all wave phenomena, not exclusively light waves. These effects can be observed in other types of waves, such as sound waves and water waves. For instance, sound waves diffract around obstacles, and water waves clearly show interference patterns when two wave sources interact.
Conclusion: Statement B is false.
Final Conclusion
Based on the analysis, Statement A is true, and Statement B is false. This corresponds to Option C.
