Question

Quantum nature can prove :

• A. Interference
• B. photoelectric effect
• C. diffraction
• D. polarization

Answer 1

Answer: (B)

photoelectric effect

Answer 2

According to quantum theory light travels in small bundles or packets of energy known as photons. The energy of photon in such case is $hv,$ where $h$ is Plancks constant and $v$ the frequency of light. The intensity of light depends on the number of these photons. Einstein explained the phenomenon of photoelectric effect on the basic of Plancks quantum theory. Note: Interference, diffraction and polarization proved the wave nature of light.
