1. A monochromatic light beam is incient on a barium target, whichhas a work function of 2.50eV. If a stopping potential of 1.5V isrequired what is the light beam photon energy (in eV)?
2. Light of wavelength 450nm is incident on a target metal whichhas a work function of 1.8eV. what stopping potential (in V) isrequired for this combination in a phototube?
