Photoelectric Current Dependency

Assertion (A): On increasing the frequency of incident light, the photoelectric current increases.
Reason (R): Photoelectric current depends upon the wavelength of incident light.
 
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Solution:

Increasing the frequency of incident light increases the kinetic energy of emitted photoelectrons, not the photoelectric current. Photoelectric current depends primarily on the intensity of the incident light, provided the frequency is above the threshold. Therefore, both assertion (A) and reason (R) are false.
