Electrons are emitted with zero velocity

Mention its one practical application in daily life. Calculate thresholds freqency V o and work function W o of the mental. Calculate threshold frequency v 0 and work function W 0 of the metal.

Electrons are emitted from an electron gun at almost zero velocity and are accelerated by an electric field E through a distance of 1. The electrons are now scattered by an atomic hydrogen sample in ground state. What should be the minimum value of E so that red light of wavelength Byju's Answer. Open in App. The given wavelength in Balmer series.

Electrons are emitted with zero velocity

Given the wavelength of radiation is. But the electrons are emitted with zero velocity from a metal surface when it is exposed to radiation. That means the kinetic energy will be zero. So, the Threshold frequency will be:. CBSE Class 12 physics board exam today; values of physical constants, weightage. Dont't have an account? Register Now. Colleges Colleges Accepting B.

Electrons are emitted with zero velocity

Electrons are one of the three basic constituents of atoms, the other two being protons and neutrons. Because electrons carry a net charge, the value of which is 1. If you know the value of this field's potential difference, you can calculate the speed or velocity of an electron moving under its influence. You may recall that in everyday physics, the kinetic energy of an object in motion is equal to 0. The corresponding equation in electromagnetics is:.
