Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): Electrons are emitted from a metal surface when the frequency of incident light is above the threshold frequency.
Reason (R): The photoelectric effect demonstrates the particle nature of light.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false but R is true.
