Light is incident on the cathode of a photocell and the stopping voltages are measured for lights of two different wavelengths as shown in data below. Determine the work function of the metal of cathode in eV. Also determine the value of the planck constant (h) from given data.
: 4000Å 4500 Å
V : 1.3 V 0.9 V
