MCQ
Which of the following effects could not be explained by Maxwell's electromagnetic wave theory?
- APhotoelectric effect
- BCompton effect
- CRaman effect
- DAll of these
✓
Answer
- All of these
Explanation:
- Photoelectric effect was discovered by heinrich Rudoy Hertz.
- Compton effect was discovered by Aethur Holl Compton.
- Raman effect was discovered by Sir Chandrasekhar Venbata Ram.
So, none of these effect was discovered by Maxwell.
