Hν = W + E.

(b) what is the stopping potential (c) if the chromium is irradiated with light of varying wavelengths, from 2000 å up through the full. If the photon's energy exceeds the threshold, the expelled electron will have surplus energy, also known as kinetic energy, when it is released. Energy of light radiation = kinetic energy of photoelectron + work function here, you are actually calculating the work function and thinking that it is the kinetic energy.

The Photoelectric Work Function Is The Minimum Photon Energy Required To Liberate An Electron From A Substance, In The Photoelectric Effect.if The Photon's Energy Is Greater Than The Substance's Work Function, Photoelectric Emission Occurs And The Electron Is Liberated From The Surface.

The work function of chromium metal is 4.4 ev. Since work function does not depend on wavelength of incident light so it will be constant for both cases. Ke = 0.5 * m * v², where:

We Know That The Kinetic Energy Of The Ejected Electron Plus The Work Function Is The Total Energy Supplied In Terms Of The Photon.

Say we also know the frequency of the photons that we aimed at the metal. Laws governing the photoelectric effect Thus, the work function can be obtained from the onsets of the photocurrent as a function of the kinetic energy of the photoelectrons.

With The Kinetic Energy Formula, You Can Estimate How Much Energy Is Needed To Move An Object.

The energy of photon = energy needed to remove an electron + kinetic energy of the emitted electron. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. Calculate the energy of the light radiation [hc/(wavelength)], where h is planck's constant and c is the speed of light.

1,2 Relative Methods Employ A Reference Made Of A Material With A Known Work Function And Focus On Measuring Differences In Electrical Quantities Between The Studied Material And The Reference.

The work function is the metal surface's threshold energy for ejecting electrons, which is commonly expressed in joules. Work function is the minimum amount of energy required to remove an electron to infinity, from the surface of a given metal.threshold frequency is the minimum frequency of the incident light which can cause the ejection of electrons without giving them additional energy. W is a work function.
