A) Photoelectric effect
B) Polarisation
C) Diffraction
D) Interference
Correct Answer: A
Solution :
Light possess dual nature, at time it behaves as a particle and at times as wave. Polarisation, diffraction and interference support the wave nature of light. While particle nature is supported by photoelectric effect, because according to Plancks hypothesis light travels in small bundles or packets of energy known as quanta, this is supported by photoelectric effect.
