No links please 16. How does (i) photoelectric current and (ii) kinetic energy of the photoelectrons emitted in a photocell vary if the intensity of the incident radiation is doubled ? [CBSE '05] Share with your friends Share 0 Pintu B. answered this Dear Student , When the intensity of incident light isdoubled , the number of photons incident on the emitter surface doubles ,hence the emitter of photoelectrons emitted also doubles causing the photo electric current also double .The kinetic energy of photoelectrons depends only on frequemcy of incident light and not on intensiy hence any change in intensity does not change the kinetic energy of the photo electrons . Regards -1 View Full Answer Ayesha Ayesha answered this Kinetic energy is independent of intensity if incident light.However the photoelectric current will increase. 0
