During the photoelectric effect, that forms the basis ofphotovoltaic solar cells, a beam of monochromatic light consistingof an unknown number of photons knock electrons out of a metalproducing an electrical current. For this effect, which statementis always true?
A. The kinetic energy of each electron depends on the intensity ofthe light beam. B.The kinetic energy of each electron depends onthe number of photons in the light beam.
C.The kinetic energy of each electron depends on the wavelength ofthe photons in the light beam.
D.All are correct.
