Question

Wave theory cannot explain the phenomena of
A) Polarization
B) Diffraction
C) Compton effect
D) Photoelectric effect

• A. A and B
• B. B and D
• C. C and D
• D. D and A

Answer 1

Answer: (C)

C and D

Wave theory can explain polarization and diffraction but could not explain compton effect and photoelectric effect. Compton effect and photoelectric effect is explain by quantum theory which treat light as particle.

So, the answer is option (C).
