WebJan 1, 2024 · What is the relation between wavelength and stopping potential? Given: Stopping potential = Vs = 2 V, wavelength of incident light = λ = 2000 Å = 2000 x 10-10 m, speed of light = c = 3 x 108 m/s, Planck’s constant = h = 6.63 x 10-34 Js, Charge on electron = e = 1.6 x 10-19 C.
WebThis minimum frequency is also called the threshold frequency, and the value of ν 0 \nu_0 ν 0 \nu, start subscript, 0, end subscript depends on the metal. For frequencies greater than ν 0 \nu_0 ν 0 \nu, start subscript, 0, end subscript, electrons would be ejected from the metal. Furthermore, the kinetic energy of the photoelectrons was ... WebApr 10, 2024 · Energy versus frequency graph. What is Stopping Potential? Stopping potential, or cut-off potential, is defined as the required potential for stopping the removal of an electron from a metal surface when the incident light energy is greater than the work potential of the metal on which the incident light is focused. The work function and ...
