Reference no: EM13521409

Ultraviolet light is incident normally on the surface of a certain substance. The binding energy of the electrons in this substance is 3.44 eV. The incident light has an intensity of 0.057 W/m2. The electrons are photoelectrically emitted with a maximum speed of 4.8 105 m/s. How many electrons are emitted from a square centimeter of the surface each second? Assume that the absorption of every photon ejects an electron.
