NEET Physics Photoelectric Effect Assertion Reason Question
Assertion (A): The photoelectric emission is an instantaneous process. | Reason (R): The energy required for electron emission can be supplied by irradiating the metal with light of suitable frequency.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The photoelectric effect is indeed instantaneous, and while the reason states a true method of supplying energy, it does not explain the instantaneous nature of the emission.
