A light source is used in a photoelectric effect experiment to determine the work function of a particular metal. When green light from a mercury lamp (546.1nm) is used, a retarding potential of 0.88V reduces the photocurrent to zero. Based on this measurement, what is the work function for this metal?

Two light sources of wavelengths λ and 2λ, respectively, are used successively in a photoelectric experiment. The corresponding stoppage potentials are 3.2 V and 0.8 V, respectively. Calculate: (a) the value of λ, in nm; (b) the work function of the metal, in eV.
in a photoelectric experiment it is found that a stopping potential of 1.00 v is needed to stop all the electrons when incident light of wavelength 294 nm is used and 2.7 V is needed for light of wavelength 207 nm. from these data determine plank's constant and the work function of thr metal.
1) Light of wavelength 310nm is shined on a metal with work function = 1 eV. What will be the maximum kinetic energy of the emitted electrons? 2) Light is shined on a metal with work function 2.0 eV, and electrons are emitted creating a photocurrent. When a decelerating voltage of magnitude 1.0 V is applied, the current goes to zero (i.e. the magnitude of the stopping voltage is 1V). What is the wavelength (in nm) of the incoming light?...
