10) A photoelectric effect experiment is done using light of some wavelength 2. The photoelectrons are observed to have a maximum kinetic energy of 7.0 eV. If the experiment is repeated using light of twice that wavelength (22 =221), on the same metal, it is found that the maximum electron kinetic energy is 2 eV. What is the work function of the metal?
Violet light of wavelength 400 nm is used in a photoelectric effect experiment that involves directing the light source at calcium that has a work function of 4.6 x 10-19 J. Determine if any electrons are emitted, and if they are, determine their maximum kinetic energy.
Problem (8 points) For the Photoelectric Effect experiment shown, when ultraviolet light with a wavelength of 240 nm shines on a particular metal plate, electrons are emitted from plate 1, crossing the gap to plate 2 and causing a current to flow through the wire connecting the two plates. The battery voltage is gradually increased until the current in the ammeter drops to zero, at which point the battery voltage is 1.40 V plate 2 AV incident ◇e electrons Tammeter...
