Which of the following phenomenon can be explained by the wave picture of light

A. Photo-electric effect
B. Compton effect
C. Polarisation
D. Diffraction

Choose the correct answer from the options given below:

C and D only

The correct answer is Option (3) → C and D only

(C) Polarization - The wave picture of light can easily explain polarization, which occurs when wave (light) oscillates in particular planes.

(D) Diffraction - It is the bending of light wave around obstacles when it passes through small opening.
