An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (30×1015 Hz to 30×1018 Hz) and energies in the range 124 eV to 124 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it on November 8, 1895. He named it X-radiation to signify an unknown type of radiation. Spellings of X-ray(s) in English include the variants x-ray(s), xray(s), and X ray(s).
I'm wondering how, for each peak in an x-ray spectra from a material (and using a crystal analyser), it is determined which energy level jump the peak corresponds to?
How would you figure out the correct value of n to substitute into Bragg's Law to find the energy of the beam?
Good morning all, I was just wondering the following question. When an electron is accelerated it emits electromagnetic radiation, depending on how much it is accelerated the energy varies so the frecuency does and the electromagnetic wave emitted would be of different colors or maybe even...
What equation would I need to use to determine the energy of photons released when radio-isotopes decay? I would like to figure out the energies of photons released when tritium and plutonium 237 decay.
Hello I had two doubts, I know that medical physicist when working with x-rays use the formula D(x)=alfa*mu*I(x)/rho
where D(x) is the dosis absorbed
Alfa is the factor of the energy that damages
Rho is the density
mu is the absorbtion coefficient
My doubt is the following: Does this formula...
Hi everyone. By reading stuff on the Internet, I found many times the correlation between machine learning and NMR, or, better, algorithms that are implemented for that kind of technology( The same goes for PET, or CT scans.
The thing I want to ask is, how much do you think that the two things...
HI everyone. I'm a student of communication systems engineering in Italy, doing his year of bachelor. What i wanted to ask, to all of you, was a doubt which I had during the last few months : choosing a carreer in Physics, or in Engineering, after getting my bachelor's degree in Engineering...
