Interference demonstrates light's: MCQ with Answer and Explanation

Interference demonstrates light's:
A. Particle nature
B. Wave nature
C. Neither
D. Both
Answer: Option B
Solution (By JKSSB Mock Tests)
Interference (constructive/destructive superposition) is wave phenomenon. Young's double-slit confirmed light's wave nature. Particle nature shown by photoelectric effect.
