Question
Please explain and show work. Thanks!
During the photoelectric effect, that forms the basis of photovoltaic solar cells, a beam of monochromatic light consisting of an unknown number of photons knock electrons out of a metal producing an electrical current. For this effect, which statement is always true?
All are correct
The kinetic energy of each electron depends on the intensity of the light beam. The kinetic energy of each electron depends on the number of photons in the light beam. The kinetic energy of each electron depends on the wavelength of the photons in the light beam.All are correct
Explanation / Answer
The kinetic energy of each electron depends on the wavelength of the photons in the light beam.
-------------------------
E = 10 MeV
hc/L = 10 x10^6 x 1.6 x 10^-19 J
wavelenght , L = 6.625 x 10^-34 * 3 x 10^8 /(16 x 10^-13) = 0.124 pm
