Electrons are emitted with zero velocity

Electrons electrons are emitted with zero velocity 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.

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.

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. Calculate i threshold frequency ii work function. Will there be photoelectric emission or not? Determine the work function of the metal, the threshold wavelength of metal and the stopping potential difference required to stoop the emission of electrons. When a certain metal was irradiated with light of frequency 1. Calculate the threshold frequency v 0 for the metal. Metal surface emits photoelectrons when light of wavelength nm is incident on it. Calculate the work function of the metal if stopping potential is 0. Calculate the de Broglie wavelength of electrons emitted with maximum kinetic energy. The work function of the metal is. Electromagnetic radiation of wavelength nm is just sufficient t A 25 watt bulb emits monochromatic yellow light of wavelength of 0.

Calculate the wavelength of an electron moving with a velocity of 2. Using s, p, d notations, describe the orbital with the following quant Calculate the wavelength of first line of Lyman series of ten times i Was this answer helpful? An atom of an element contains 29 electrons and 35 neutrons. Latest Question A sum of money under compound interest doubles itself in 4 years.

Being fermions , no two electrons can occupy the same quantum state , per the Pauli exclusion principle. The wave properties of electrons are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a longer de Broglie wavelength for a given energy.
