Compton effect Definition and 67 Threads

oK SO... I have been given the task of deriving the Compton effect equ. ( \lambda\prime-\lambda=\frac{h}{m_ec}(1-cos\theta)) exactly from the 3 following: 1) \frac{h}{\lambda}=\frac{h}{\lambda\prime}cos\theta +\gamma m u cos\phi 2) 0=\frac{h}{\lambda\prime}sin\theta-\gamma mu sin\phi...

what is the area of usage of compton effect,why do we use it and where do we use?what is the importance of it?please help me!

I know this topic has already been covered many times, but, is it possible to explain classically or semiclassicaly the standard Compton effect?

Hi everyone, Right now, I am working on a homework problem asking me to derive the Compton effect, which is given by \lambda\prime-\lambda=\frac{h}{m_ec}(1-cos\theta) A diagram of the situation can be found here: http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/compton.html#c1...

In the Compton effect, a 0.100nm photon strikes a free electron in a head-on collision and knocks it into the forward direction. The rebounding of the photon recoils it directly backward. Use conservation of (relativistic) energy and momentum to determine: a) the kinetic energy of the electron...

How do I find the endpoint energy for photons when an .75 MeV electron beams stops inside a tungsten target? I just don't understand how to solve it without the scattering angle.:confused:

I have an odd problem here. I need to show that: KE = \frac{{\frac{{\Delta \lambda }}{\lambda }}}{{1 + (\frac{{\Delta \lambda }}{\lambda })}}hf I've basically derived KE = \frac{{hc}}{{\lambda _o }} - \frac{{hc}}{{\lambda '}} down to… KE(\frac{{\lambda '}}{{\lambda _o ^2 }}) =...

why is it extremely dificult to observe the compton effect using visible light? is it because visible light does not have a short enough wavelenght to excite the electrons?

for the following question: for electromagnetic waves A of wavelength 10pm and electromagnetic waves B o f wavelengthh 20 pm, which produces more pronounced Compton effect? my problem: the question doesn't give the scattering angle or final wavelength, so isn't this question too ambiguous?

for the following question: x-rays scattered by a crystal are assumed to undergo no change in wavelength. show that this assumption is reasonable by calculating the compton wavelength of a Na atom and comparing it with the typical x-ray wavelength of 0.1nm. my problems: 1) why doesn't...

How can a photon knock an electron from a shell, entirely out of the atom? (i.e PhotoElectric Effect) Photons have 0 rest mass, and little relativistic mass? For force, F = ma For example, let m = negligable (like the photon's mass is) mass so = mn If F = (mn)a and mn is small...

Here's what I know... the xray hits an electron and the electron goes of at some angle, with the xray deflecting the other way. I was curious if a certain portion of the electric versus the magnetic waves are transferred into the electron for momentum and another portion for the new(is it a new...

It appears more and more people are challenging the traditional interpretation of the Compton/Photoelectric Effects. Cramer back in 1986 used the Hanbury-Brown-Twiss effect to show that there is not a 1:1 correspondence between the emitted and dected quanta. You have to combine fractions of...

In the Rutherford scattering experiment a very thin gold foil target is bombarded with a beam of a particles of known kinetic energy. A detector which can be moved on a circle around the target counts the scattered particles. What was the impact parameter of a 4.57 MeV a particle if it was...

A photon having E = 14.7 keV energy scatters from a free electron inside a metal. What is the maximum energy the electron can gain from the photon? Lamda'-lamda= change in lamda = h/mc (1-cos(theta)) ...having problems figuring out theta ... I know E=hc/lamda so lamda = hc/E ...so...

Suppose you have some thin film of pure carbon graphite sitting on some metal, like iron. Now we start irradiating some EM energy on it the graphite, but at a specific frequency. Is it possible to select a frequency, and potentially some sort of spread/interference pattern to the EM energy...

Hi,I need some help here. Why the Compton effect can not be noticed when we are using light from the visible spectrum?
