An electron and proton have the same de-Broglie wavelength. Then the kinetic energy of the electron is AZero BInfinity CEqual to the kinetic energy of the proton DGreater than the kinetic energy of the protonSubmit An electron with speed v and a photon with speed c have the same de-B...
An electron is in excited state in a hydrogen-like atom. It has a total energy of−3.4eV.The kinetic energy of the electron is E and its de Broglie wavelength isλ View Solution When photon of energy25eVstrike the surface of a metal A, the ejected photelectron have the maximum kinetic...
Photo energy is more common than electron energy in AM because it does not require a vacuum environment. Photon energy is quantum energy carried by a single photon. It is used to trigger polymerization or to heat polymers. The power density is the product of photon energy and photon flux, ...
Electron energy-loss spectroscopy (EELS) is an analysis of the distribution of electron energy emergent from a thin specimen due to inelastic interactions.

iThe energy of the photon is not enough to excite the electron to energy #Thus the electron remain in its ground state and photon is not absorbed fifty-three photon remain unchanged [B1]iiThe energy of the photon is enough to ionise the atom ÷ to remove the electron from the atom. @...
An electron releases a photon as a means of expelling excess energy. This energy, which comes from excess energy in the atom, forces the electrons to...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your ...
One of our original motivations was the question of whether noncommutativity allows photon creation by intense electromagnetic fields (the effects of noncommutativity on electron/positron production by strong electric fields can be found in [4]). Although the answer requires a quantum field theoretic ...
一道英文的物理题When a proton captures an electron,a photon with anenergy of 13.6 eV is emitted.What is the frequency of thisphoton?Does it lie in,above,or below the visible range?答案 当一个质子捕获一个电子时,会发射出一个具有13.6电子伏能量的光子,请问这个光子的频率是多少?它是否在可见光...
In particular, it has been shown that the power consumption from the driver amplifier can dominate the overall power breakdown25, and models have demonstrated that the driver’s energy efficiency gets worse when operating at a higher data rate26. These models indicate the importance of ...
An electron and alpha particle have the same de-Broglie wavelength associated with them. How are their kinetic energies related to each other ? View Solution An electron and a photon have got the same de- Broglie wavelength. Prove that total energy of electron is greater than energy of photon...
