The energy spent in releasing a photoelectron is called photoelectric `"______________"` of the metal.

Define: (i) photoelectron and (ii) photoelectric current

What is photoelectric effect? What are photoelectrons?

Photoelectric effect When light of sufficiently small wavelength is incident on a metal cathode, it may emit electsons called photoelectrons. This is called photoelectric effect. Above threshold frequency, the stopping potential and hence the energy of the photoelectrons is directly proportional to the frequency. Slope of graph is given by

Photoelectric effect When light of sufficiently small wavelength is incident on a metal cathode, it may emit electsons called photoelectrons. This is called photoelectric effect. Above threshold frequency, the stopping potential and hence the energy of the photoelectrons is directly proportional to the frequency. In the given figure, we see the variation of stopping potential with the frquency of incident radiation for three metals A, B and C Which of these metals A, B or C are suitable for photoelectric cell?

Reaction that releases energy is called Enodothermic.

Photoelectric effect When light of sufficeintly small wavelength is incident on a metal cathode, it may emit electons called photoelectrons. Above threshold frequency the stopping potenital and hence the energy of the photoelectrons are directly proportional to the frequency. in the given figure, we see the variation of stopping potential with the frequency of incident radiation for three metals A, B and C. Which of these metals A, B or C are suitable for photoelectric cell?

The number of photoelectrons in a photoelectric effect experiment depends on the
