Why does the intensity of Bremsstrahlung radiation increase with lower energy?

In summary, the spectrum of Bremsstrahlung radiation is continuous and varies with the energy of the accelerated particles. At lower energies, there will be a higher number of low-energy events, leading to more intense radiation. The Larmor formula is used to calculate the total power radiated by a non-relativistic point charge, while the second reference also considers the case of relativistic particles. Thus, the two spectra will match at low energies but differ at high energies.

In the above link, it says that "you will count more low-energy events since they are more probable." Which must mean that at lower energy we must get more intense radiation.

https://en.wikipedia.org/wiki/Bremsstrahlung

In this article, it is said that " peak intensity shifts toward higher frequencies as the change of the energy of the accelerated particles increases."

Which one is correct? Or are they both conveying some different message?

The second reference which you mention analyze also the case of relativistic particles and therefore the two spectra will match at low energies but will disagree at high energies.

Related to Why does the intensity of Bremsstrahlung radiation increase with lower energy?

1. What is Bremsstrahlung intensity?

Bremsstrahlung intensity refers to the amount of radiation emitted by a charged particle as it decelerates or changes direction. This radiation is produced when an electron is deflected by the electric field of an atom's nucleus, causing it to lose energy in the form of photons.

2. How is Bremsstrahlung intensity measured?

Bremsstrahlung intensity is typically measured in units of energy per unit time, such as watts or electron volts per second. It can also be measured in terms of the number of photons emitted per unit time.

3. What factors affect Bremsstrahlung intensity?

The intensity of Bremsstrahlung radiation is affected by the energy and charge of the charged particle, as well as the strength of the electric field it is passing through. The atomic number of the target material and the angle of deflection also play a role in determining the intensity.

4. What is the relationship between energy and Bremsstrahlung intensity?

The intensity of Bremsstrahlung radiation increases as the energy of the charged particle increases. This is because higher energy particles have a greater chance of interacting with the electric field of the nucleus, resulting in more radiation being emitted.

5. How is Bremsstrahlung intensity used in scientific research?

Bremsstrahlung intensity is commonly used in fields such as atomic and nuclear physics, as well as medical imaging. It can also be used to study the properties of materials, such as their elemental composition and crystal structure.
