MCQ
The following cannot be explained by wave nature of light:
- AInterference
- ✓Photo electric effect
- CDiffraction
- DRefraction
✓
Answer
Correct option: B.
Photo electric effect
Photo electric effect
According to wave physics energy of a wave depends upon an amplitude of a wave it means that there light of any frequency can make electrons come out from metal but it did not happen, light of certain fixed frequency can make electron come out from metal. So the photoelectric effect can only be explained by particle nature of light not wave.
