Photoelectric effect reveals the :
- A wave nature of radiation
- B particle nature of radiation
- C both wave and particle nature of radiation
- D electromagnetic nature of radiation
Answer & Solution
Correct Answer
(B) particle nature of radiation
Step-by-step Solution
Detailed explanation
The photoelectric effect demonstrates that light consists of discrete packets of energy called photons. Because classical wave theory fails to explain why electron emission is instantaneous and dependent on frequency rather than intensity, it serves as primary evidence for…
