Assertion (A): In photoelectric effect, on increasing the intensity of light, both the number of electrons emitted and kinetic energy of each of them get increased but photoelectric current remains unchanged.
Reason (R): The photoelectric current depends only on wavelength of light.
(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)
(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(3) (A) is true but (R) is false
(4) Both (A) and (R) are false
Solution:
Assertion (A) is false: Increasing intensity increases number of electrons and current, but KE remains same. Reason (R) is false: Photoelectric current depends on intensity and frequency. Both statements are false.
