Question

According to Maxwell's electromagnetic theory following phenomenon can be explained.
I. propagation of light in vaccum
II. interference of light
III. polarisation of light
IV. photoelectric effect

• A. I, II and III
• B. I, II, IV
• C. I, III and IV
• D. II, III and IV

Answer 1

Answer: (A)

Except photoelectric effect, all others phenomenon such as propagation of light in vacuum, interference and polarisation of light can be explained by wave theory of light. In photoelectric effect light behaves as it is made up of particles.
