Observations from an experiment on photoelectric effect for the stopping potential by varying the incident frequency were plotted. The slope of the linear curve was found to be approximately 4.1 × 10-15 V s. Given that the charge of an electron is 1.6 × 10-19 C, find the value of the Planck’s constant h.

Answer»

Data : Slope = 4.1 × 10-15 V∙s, e = 1.6 ×10-19 C

Ve = hv – hv0

V = \((\cfrac{h}{e})\)v - \((\cfrac{hv_0}{e})\)

∴ Slope = \(\cfrac{h}{e}\)

∴  Planck’s constant,

h = (slope) (e) = (4.1 × 10-15 V∙s)(1.6 × 10-19 C)

= 6.56 × 10 34 J. (as 1 V = \(\cfrac{1J}{1C}\))
