Particle Physics (24 of 41) What is a Photon? 8. How Are X-Rays Produced?

In this video I will explain how x-rays are produced by photons.

Next video in the Particle Physics series can be seen at:

Thank you professor. I have a never ending thirst for knowledge and this helps understand X-rays better.

It should be strongly emphasized that the electron that was originally knocked-out is from the the inner most shell and not just from any shell.

Hi there, It's always fuzzy for me when ppl say a "photon" of light is released then ALWAYS draw a squiggly in
just "one direction". For illustration purposes I can see why, but the fuzziness for me is, in actuality, DOESN'T
that light radiation go out in ALL DIRECTIONS not just one linear direction? That is, if we have 5 people
observing the photon of light, one in front, one 90° left, right, up, down...don't all 5 ppl see that wave of light?
Teachers never mention or indicate the the light goes in all directions...always just one direction. As if. if you
were not in front of that photo of light you would not be able to see it. Is that true or false? Can anyone help?

Thanks for the great explanation. For diagnostic X-rays bremstralung is actually the vast majority of the X-rays and determines the system characteristics.

[fungkeat]

What is the characteristics line of the continuous line spectrum ?

Now I know that Jason Statham has a second job as a physics teacher.

It should be strongly emphasized that the electron that was originally knocked-out came from the the inner most shell and not just from any shell.

For Linear Accelerators (LINAC) used for Radiation Therapy the same process is used, is that correct? However, I was wondering why LINAC can produce a much higher energy photon beam than normal x-rays? Is it because the electrons are accelerated, and thus when it is slowed down it releases higher energy x-rays?

What happens to the electrons that were knocked out where do they go? What happens to the electrons in the higher orbitals that are knocked out of orbit, I am sure they release photons as well as they are replaced, but also when an electron is filled in, there is a missing electron in the outer shells of tungsten and so forth, now they are not electrically neutral or ionized. What happens then? What are those implications?

[asifmirza]

Please let know what happened to anode metal atom when electron from cathode knock out the electron from anode atom and produce x ray, does anode atom goes positive ionized???

[RiyaTomar-jdmw]

Just a suggestion to you sir, instead of writing the values of h and c again and again in the formula of wavelength [ lambda= hc/E] and then converting it to nano meters by dividing it by a factor of 1.6 x 10^-19, you can simply use this - lambda= 1242/E. This directly gives you the wavelength in nanometers . ( i use this a lot cuz this saves time and i was taught this during the preparation of JEE ) .

[vijgenboom]

This lesson is again another great one! Thank you sir.

[tiwarykhan]

Why cathode rays slow down and emits energy when they passes near to the nucleus of anode ?

[lydiag.]

Am I getting it wrong? To achieve the pm we need to use 593000 (answer 2.095pm) but should not it be 59300 and the actual answer would be 0.21pm
Any clarification would be appreciated.

[patasjunior]

The wave length should be in pm and not in nm.

[MayurDattatraySherkhane]

Why only inner most electron in W/Mo got knocked out? Why not any other orbital electron?

Thanks in advance.

[delanechigwangwa]

You are very sharp and precise, thank you

Shouldn't the title be "Particle Physics (24 of 37) What is a Photon? 8. How Are X-Rays Produced by Electrons?"

[manaral-tamimi]

you just made life easier thankkkk uuuu!!

[omerfaruksadak]

I have a question, sir. What happens when we increase the voltage of the tube? We increase the energy of emitted electrons but since the wavelengths of the x-rays depend on the material and they are known based on the kEV, how can increasing the voltage may affect the system?
