The phenomenon of interference of light demonstrates that light has: MCQ with Answer and Explanation

Interference (constructive/destructive superposition) is a characteristic wave phenomenon, requiring coherent sources and path difference. Young's double-slit experiment demonstrated light interference, confirming its wave nature. Particle nature is shown by photoelectric effect. Memory aid: 'Interference/diffraction ⇒ wave nature; photoelectric effect ⇒ particle nature'. This conceptual question tests wave-particle duality fundamentals, frequently examined in competitive exams. Always link specific phenomena to the aspect of light they demonstrate; competitive exams often combine both aspects in advanced questions.
