Awasome Work Function And Threshold Frequency 2022

The Least Energy Which Can Eject The Electrons From The Surface Of The Metal.

The equation for work function is w = hf so this is rearranged to. Work function is the minimum energy required to remove an electron from an atom. Electrons are, therefore, emitted only if the frequency of the photon is.

Work Function Is Different For Different Metals.

Threshold frequency is the minimum frequency of incident light which causes the metal surface to emit electrons. Calculate the threshold frequency for a metal with a work function of 3ev. Let us use the relation between the frequency and the wavelength of light, i.e.

Best Answer (I) Work Function Is The Minimum Energy Of Light Radiations Required To Remove An Electron From The Metal Surface.

• work function is measured in joules or electron volts, but the threshold frequency is measured in hertz. The minimum value of the frequency of light to give the work function is called the threshold frequency. Therefore if we know the work fucntion we can work out the threshold frequency but don’t forget to convert 3ev into j.

Therefore If We Know The Work Fucntion We Can Work Out The Threshold Frequency But Don’t Forget To Convert 3Ev Into J.

Calculate the threshold frequency and threshold wavelength of silver. Answered aug 7, 2017 by faiz (304k points) selected aug 7, 2017 by sforrest072. Where , ν o is threshold frequency.

The Threshold Frequency Is That Minimum Frequency Of Light Below Which The Photoelectrons Do Not Emit.

Photoelectric effect, work function, threshold frequency, wavelength, speed. The photoelectric effect provides important evidence that light is quantised or carried in discrete packets. F = w/h where h is planck’s constant.
