I don't get what the text supposes to mean then. Where it states "generally", i see "with the same speed", which isn't so general. Is there something basic I'm missing?

How being a lepton/meson/hadron influence the effect of Moliére multiple scattering? It doesn't include strong interactions. As I pointed out, single scattering cross section goes with (m/p2)2, so it just depends on mass (for particles "of a given energy")...but in the opposite way in respect to...

The context, as I said, defines the concept of particle range. Quote: "Experimentally, the range can be determined by passing a beam of particles at the desired energy through different thicknesses of the material in question and measuring the ratio of transmitted to incident particles.". The...

Which is exactly the opposite of what the book says and the same thing I was pointing out. This doesn't answer my question. The effect of scattering may be smaller for heavier particles with the same VELOCITY of lighter ones, but velocty isn't usually a term for comparison. The context from...

What is the dependence between multiple scattering (Moliére formula) and the mass of incident particles? I'm reading on my book: "the effect of multiple scattering is generally small for heavy charged particles" but I really can't find a correlation with mass in the Molière formula, while the...

So, if the detector is in contact with the material, the particle radiates until it reaches the detector, and the detector is just a plain sheet of PMs, what we'll see is actually a full circle, right?

Do you know how light/particle detectors work? Fig. 2 is a ring, because only border detectors are activated, while inner detectors are off as well as outer ones. I'm asking, if the wave front is continuous, from the axis of the cone, to the maximum radius of the projection, why the image is not...

In order to formalize what "twisting" is, let's divide the rod in slices, each one with same thickness. For example, each slice is thick as the distance between two consecutive black arrows. If you twist the rod moving only the top and leaving the bottom still, you are rotating the top slice of...

I hope I'll help. If you trace a line (for semplicity, a vertical, straight line, without lo ss of generality) on an un-twisted rod, and then you twist it (for example, leaving the bottom still and moving the top), supposing the twisting homogeneus, the line will be distorted like in the figure...

Biomedical Physics, but I'm still studying, so I may post threads about just anything.

i.e. "Hello physicists!" in Italian. I'm Antonio, student. Very often I realize during my studies that something misses, something basilar here, a simple information there, that somehow are so obvious that they're impossible to find. I like go deep in things, this is why I'm here :) Greetings. A.R.

If the image we obtain from Cherenkov light is actually the projection of a continuous wave front (Fig. 1) on a vertical plane, orthogonal respect to the direction of propagation of the incident particle, why we just see a ring (Fig. 2), instead of a full circle? Is it because Cherenkov light is...
