![]() ![]() We have the feet of like equals mm three times 10 to the eight m per second. We have the mass of our electron equals 9.11 times 10-31 kilograms. The problem gives us that our initial we've length for our proton equals 0.400 meters. All right, so let me write down our physical quantities. So, you know, that is 9.1, 1 times 10 -31 kilograms Time to feed of light, which everyone knows is three times 10 to the eight m second uh data here is the angle at which the photon rebounds after the collision. And is a mass of the particle that is involved in the collision. Which we know is what two Times 10 -34, Two times second. The shift in wavelength of the photon is measured for various scattering angles and the results are plotted on the graph shown below.a On the graph sketch a. We've lined up our photons land uh initial is our incoming wavelength of a photon, H is Planck's constant. Okay, we're our lambda s s is are scattered. Um luckily we have a simple formula here where we have our scattered wavelengths for photons equals our initial wavelengths plus aah and oversee times 1- Co sign of data speed and not keep. What we want to do is find the wavelength of the scattered photons after it, it collides with the electron. We know it's a particle and no ways it's going to hit an electron and scatter off in some direction. What we want to do is we're given it it's i it's I mean the photons wave length and speed coming in call this my proton proton. Contrary to this prediction of classical. ![]() The effect has proved to be one of the cornerstones of quantum mechanics, which accounts for both. By classical theory, when an electromagnetic wave is scattered off atoms, the wavelength of the scattered radiation is expected to be the same as the wavelength of the incident radiation. Compton effect, also called Compton scattering, increase in wavelength of X-rays and other energetic electromagnetic radiations that have been elastically scattered by electrons it is a principal way in which radiant energy is absorbed in matter. Inverse Compton scattering also exists, where the photon gains energy (decreasing in wavelength) upon interaction with matter. The Compton effect is the term used for an unusual result observed when X-rays are scattered on some materials. Um What compton scattering is, is it measures various quantities when a proton interacts with a charged particle, in our case, we're looking at a proton single proton interacting with the an electron. In physics, Compton scattering or the Compton effect is the decrease in energy (increase in wavelength) of an X-ray or gamma ray photon, when it interacts with matter. lambda - lambda h/(m e c) (1 - cos theta) The value h /( m e c ) is called the Compton wavelength of the electron and has a value of 0. I'm going to be looking at a simple example of constant scattering. is equivalent to carrying out the rotations YQK(theta. First, we need to convert the given wavelength from nanometers to meters. Compton scattering provides a projection of the electron momentum. ![]()
