A mercury lamp is a convenient source for studying frequency dependence of photoelectric emission, since, it gives a number of spectral lines ranging from the UV to the red end of the visible spectrum. In our experiment with rubidium photo-cell, the following lines from a mercury source were used: lambda_1 = 3650 oversetcircA , lambda_2=4047 oversetcircA , lambda_3=4358 oversetcircA , lambda_4=5461 oversetcircA , lambda_5=6907 oversetcircA The stopping voltages respectively were measured to be V_0=1.28 V , V_0.95V , V_0=0.74V , V_0=0.16 , V_0=0V Determine the value of Planck's constant h.

In an experiment on photoelectric effect, the slope of the cut-off voltage versus frequency of incident light is found to be 4.12 xx 10^-15 Vs . Calculate the value of Planck's constant.

The figure shows the stopping potential for the phototelectron versus (1/lambda) graph for two metals A and B, lambda being the wavelength of incident light How is the value of Planck's constant determined from the graph?
