What is the de Brogile wavelength of an electron whose kinetic energy is 120ev?
HassanHameed
The wavelength is w=hc/E= 1.25E-6evm/120 = 10.4 nanometer.

When an electron is ejected from the surface what type of energy does the electron possess?
It is moving, so it has kinetic energy.
What is kinetic energy and what is an example of a kinetic energy?
The energy from any type of movement. Anything from a swinging swing to a Electron moving around the nucleus.
Why the kinetic energy of the emitted electrons varies up to a maximum value?
Let the work function of a metal be W. Let C be a constant of the dimension of energy. if Kis the maximum kinetic energy of an electron then.......W=C-K..... (K HERE IS THE ENERGY SUPLIED BY A PHOTON TO THE ELECTRON)
Which factor provides kinetic energy of an electron?
Kinetic energy is another name for scalar energy. Kinetic energy is provided by the vector energy cmV=cP, the momentum energy. Momentum is a vector and Momentum energy cP is also a vector, a vector energy. This Momentum Energy gives the velocity V and speed v and thus the "kinetic energy". The electron vector energy is cmV=cP and and the scalar energy is vp ! it is clear that te sclar energy vp=mv2 is much smaller than the vector energy cVm. the so-called kinetic energy is vp/2 = 1/2 mv2. kinetic energy is a product of the vector energy cmV, no Velocity , no kinetic energy.
Why drift velocity increases on increasing temperature?
because the kinetic energy of electron increase with increase in temperature. this increase in kinetic energy increase drift velocity
When an electron is ejected from the surface what type of energy does the electron possess?
It is moving, so it has kinetic energy.
Why is a shorter wavelength of light emitted when an electron falls from n4 to n1 than when an electron falls from n2 to n1?
The shorter the wave length the more energy. The further the electron falls, the more energy that will be emitted and the shorter the wavelength.
What is more- potential energy or kinetic energy of an electron in hydrogen atom?
Both are equal.
What is kinetic energy and what is an example of a kinetic energy?
The energy from any type of movement. Anything from a swinging swing to a Electron moving around the nucleus.
Is total energy of revolving electron in an atom zero?
actually total energy is the sum of potential energy and kinetic energy....potential energy= -2*kinetic energy . By using this relation you will get that sum of potential and kinetic energy is equal to the magnitude of kinetic energy and it is less than zero...hope this will be enough for you....

How x-ray mass absorption can help in getting near monochromatic x-ray beam for xrd?
The structured absorption on the high-energy side of an x-ray absorption edge. The absorption edges for an element are http://www.answers.com/topic/abrupt increases in x-ray absorption that occur when the energy of the incident x-ray matches the binding energy of a core electron (typically a 1s or a 2p electron). For x-ray energies above the edge energy, a core electron is ejected from the atom. The ejected core electron can be thought of as a spherical wave propagating outward from the absorbing atom. The photoelectron http://www.answers.com/topic/wavelength is determined by its kinetic energy, which is in turn determined by the difference between the incident x-ray energy and the core-electron binding energy. As the x-ray energy increases, the kinetic energy of the http://www.answers.com/topic/photoelectron increases, and thus its wavelength decreases.

When an electron in atom changes energy states a photon is emitted If the photon has a wavelength of 550 nm how did the energy of the electron change?
electron lost 3.6 x 10-19 -barbie=]
Is Zeke a scrabble word?
No, because it is an acronym for "Zero Electron Kinetic Energy".
Why is a shorter wavelength of light emitted when an electron falls from n equals 4 to n equals 1 than when an electron falls from n equals 2 to n equals 1?
Shorter wavelength = more energy. The farther the electron falls, the more energy that will be emitted.
Why drift velocity increases on increasing temperature?
because the kinetic energy of electron increase with increase in temperature. this increase in kinetic energy increase drift velocity
