An experiment is conducted to investigate the photo electric effect. When light of frequency 1.0 x 1015 Hz isincident on a photocathode, electrons are emitted. Current due to these electrons can be cut off with a 1.0 V stopping potential. Light of frequency 1.5 x 1015Hz produces a photoelectric current that can be cut off with a 3.0 V stopping potential
Calculate an experimental value of Planck's constant based on this data
Calculate the work function of the photocathode
Will electrons be emitted from the photocathode when greenlight of wavelength 5.0 x 10-7 meter is incidenton the photocathode? Justify answer.
