3lecs in 10 mins that was insane ,thank you so much !

[@radiologytutorials]

Glad it was helpful 🙂

[@eternalmusic8459]

Wtf! How can you make it so simple, in our JEE ADVANCE exam this part is nearly briefly touched by the teachers but the questions are asked which requires conceprual clarity which I wasn't getting but this 2 videos of x-ray are just mind blowing, no crap talk no promotion straight to topic, loved them so much man and thanks a lot❤

[@fazaltahir4216]

As always very important tpoic from radiology physics,,, and very nicely presented 🎁,,, excellent explanation

[@social.2184]

My 3 weeks lecture in a single video. Words can't describe my appreciation for you!!

[@annastasiamuma5332]

The way you are calm in teaching i understand everything thank u

[@sadafaamir9753]

Kindly make a book of your mcqs bank and publish it. Some of the residents like me need something in written. Highly Appreciate your work.❤

[@SarahPetre-d4v]

This has broken it down and I feel so thankful for your message and knowledge because I FINALLY understand! Thank you

[@ashdos7205]

wow this is amazing! saving me in medical physics

[@joviapraise846]

Hv been searching for an understandable explanation but i hd failed until i landed on you bravo👏👏

[@radiologytutorials]

So glad you found the video and that it helped!

[@prasheedhaa4234]

Thank u for the best explanation.... It's really helping to understand concepts clearly

[@radiologytutorials]

I’m glad it’s helping with understanding ☺️ no need to get too detailed just need the fundamentals 🙌🏼

[@aggelinit]

The words can’t describe how thankful I am for your great work 👏👏👏

[@uguryanc9340]

Teşekkürler.

[@radiologytutorials]

Thank you 🙏🏻

[@ibphysicsclassroom]

Best teacher in radiology you have no match bro. I'm a Ghanaian A Level physics and was struggling to teach medical physics but now I know more than the curriculum requirements and my confidence has really grown. my little problem is where to get these interactive slides you are using. please let me know what you are using

[@CDiarr]

Very well explained!

[@radiologytutorials]

Thank you Diar ☺️

[@amandahiya8067]

Please cover whole radiology like this

[@radiologytutorials]

That's my plan Aman 🙂

[@caraenachecatalin7614]

these videos are soo soo good❤❤❤

[@radiologytutorials]

Thank you Caraenache 🙏🏻❤️

[@NilCerenYldrm]

Omg, too clear thank you 🎉

[@ryamamarat]

Thank you for this amazing explanation 🙏

[@Walaasun]

Amazing! Thank you!

[@Zeinaa159]

That was amazing thank you

[@malekchtioui3107]

very comprehensible course thank you

[@tharushimunasinghe1716]

Thank you soomuch sir ❤🙏

[@toudakebbou6183]

Thank you so much for your explanation. I have a question, I might have missed something. The energy of the bombarding electron must be higher than Ek (60) in order to release an electron. Ex: 100. So the energy used in releasing from K shell is 69. The photon released from L shell going to K shell has an energy of (Ek - El). But where does the fraction of energy (100 - 69) go?

[@radiologytutorials]

Great question. The left over energy remains with the incident electron in the form of kinetic energy. The incident (aka bombarding electron) only transfers the energy needed to release the k shell electron. It rebounds off the k shell electron and travels with the remaining energy. Hope that makes sense 🙂

[@sawanisadeera1915]

Thank u so much Sir..♥️

[@countryside1037]

i didn't understand one thing. As incident electron have to remove electron from K shell of tungsten to start charactersic radiation spectrum, and we know the incident electrons are dependent on the Kvp. So howcome changing kvp doesnt effect characteristics photons?

[@dhathriprasad7121]

Sir..How a less binding energy shell electron if moved into a high binding energy electron shell will dissipate energy??..Your vidoes are jus amazing and awesome sir...Thank u

[@radiologytutorials]

Great question. The binding energy is the energy needed to remove the electron from that particular shell. It is not the actual energy of the electron (a sum of the kinetic and potential energy). The total/actual energy of electrons increases in shells further away from the nucleus. Therefore when an electron goes from an outer to an inner shell it is said to go from a high energy to lower energy state (this is completely separate from binding energy). Hope that makes sense 🙂

[@MunibahAbba]

@@radiologytutorials omg, thanks alot, you just gave an answer to a question I was about to ask. It had me confused for like a whole semester, I used to think the binding energies were directly proportional to the actual electron energies.

[@PrashathSiva]

@@radiologytutorials Great

[@sharp_guy2310]

​@@radiologytutorials Hi sir great explanation. I have a doubt. Say an electron moves from L shell where it had high PE and low KE to K shell where it gonna have high KE and low PE, Mostly as per conservation of energy the high PE converts to KE and low KE to PE.Now where energy is released for spectrum. Note KE is kinetic energy and PE is potential energy.

[@Elyrion4409]

In characteristic radiation, when the incident electron is deflected off the K shell electron, can it subsequently go and ionize other atoms?

[@ShamimHossen41]

Thank u😊

[@franziskamuhlhoff4587]

Is the characteristic radiation the same as the photoelectric effect?

[@tiffanytiffany4367]

Does the loss of the electron cause the atom to ionise?

[@juvinalboadu-ih7qf]

Awesome

[@biliibalaaa5747]

sir, i still don't really understand what is the difference between projectile electrons and ejected electrons? Thank you so much

[@megan8232]

what about KE of incident electron equals to binding energy of electron between two shells? would the incident electron replace electron in atom? will photons be released?

[@emmanuelmakinde07]

Please Is Characteristic Radiation only produced when an electron strikes the K shell electron? Or it can occur when the L or M shells are struck?

[@radiologytutorials]

It does occur but these are extremely low energy characteristic X-rays (the difference in binding energy at the outer shells is very small). They will not make it past the inherent filtration of the tube and therefore won’t reach the patient.

[@bessong-ojongwillington8400]

Great stuff

[@radiologytutorials]

Thank you 👊🏼

[@emiliasalas1447]

thanks.

[@whitewalker5791]

What is potential difference?

[@radiologytutorials]

Potential difference is the relative voltage difference between the cathode and the anode. It is also called tube potential or kVp. It is responsible for accelerating electrons across the tube.
