Physics of How Wilhelm Roentgen Discovered X-rays

[@randomscience4k]

Just found out this channel while I was looking for more history on radioactive materials and x-rays. There aren't many podcasts or videos like this about x-rays and it's history. Really enjoying the videos!!

When a HS senior in 1964, a classmate and myself found an old cold cathode X-Ray tube in the physics lab storeroom. The physics teacher gave us permission to see if we could get it to work. My friend and I designed a power supply using an old neon sign transformer and a 1B3 HV rectifier tube from a B&W TV. Out first try of taking a X-Ray of a leather key holder using a sheet of 4X5 Kodak Verichrome film did not work. The film, when developed, showed no sign of being exposed. For our second try, we put a sheet of phosphorescent paper in with the film. This time the outline of the leather key holder with the keys inside were clearly visible. The teacher was impressed as he did not think that we could get it to work.

😮😮😮😮wow!!!

"I have seen my death" - with 15 minutes of X-ray exposure, it's quite possible!

[@Kathy_Loves_Physics]

proudsnowtiger ha! Luckily for Bertha her husband’s x-ray machine produced very little x-rays so it wasn’tu as dangerous as it sounds.

In german speaking countries, the X-rays are called Roentgen rays and the process itself is described by the verb roentgen. Thank you for the very interesting video!

[@regaloma5486]

Same in Poland 🙂

[@kevgermany]

Thanks. Did you know that German hospitals don't have x-ray departments? It's always the Roentgen department.

Top of the week to you Katy. I have to say your youtube channel is my favourite programme about science, since cosmos a spacetime odyssey, love what you have done.

[@Kathy_Loves_Physics]

LFA the Movie That is such a lovely compliment, thank you!

[@Sahrwby_official]

I'm a graduate student and I loved this video, it helped me a lot to comprehend the X-rays. Greetings from Brazil!

[@Kathy_Loves_Physics]

Greetings so glad you liked it and good luck with your schooling

[@Sahrwby_official]

@@Kathy_Loves_Physics Thank you!

[@penetibalaji2277]

Thank u so much madam u are a great teacher,I missed a teacher like u 😭in my school and college days

[@LadyAnuB]

The most interesting X-ray I had was the whole mouth one done for my wisdom teethe extraction. I don't remember the X-ray procedure all that much as these taken just before I had my wisdom teeth were pulled. The extraction was a breeze as two of them had already erupted and the other two had grown in place in a vertical orientation. I was driving 4 hours after surgery and I went to the fair the next day. This was done a week before I went into the US Army.

[@debaosaghae]

Thank you for this. Please don’t give up!

[@Kathy_Loves_Physics]

Deba Osaghae glad you liked it. Am slower these days as I am homeschooling my two little ones but still working on it.

[@이말러]

Good video for comprehensive explanation on the scientific process of Roentgen's discovery. Really helpful!

[@Kathy_Loves_Physics]

이재혁 glad you liked it

[@nadeemabbasi5340]

Just accidentally found this channel 😮 same way as XRays were found😊😅 learnt something interesting today

[@aaryashukla8404]

Very nice video enjoyed watching this and Kathy is awesome

[@pedzsan]

Lets go!!! 😂 The intro music is wonderful as well.

[@tomarnd8724]

I was born on the 100th anniversary of the discovery of X-rays. TIL

[@Go_for_it652]

In my humble opinion those who succeeded in physics are the messengers of creation .

[@dosomething3]

so become one yourself ❤😮😊

[@akshaybkn]

your all videos are very interesting and informative

[@Kathy_Loves_Physics]

Physics by Akshay so glad you enjoyed them

[@wackyvorlon]

That is a fascinating video.

[@Kathy_Loves_Physics]

Thanks, glad you liked it.

[@amitpatil5151]

Good Video, Learned Something New in Fun Way. I liked it. Your Narration is Good.

[@Kathy_Loves_Physics]

AMIT PATIL so glad you liked it

[@shantanusingh3961]

Excellent

[@NoMore4YearsofFailur]

Very interesting.....I loved it.

[@minkmink2166]

Thank you for explaining I edge to your videos! 🥰🥰😍😍🤩

[@johannesnurnberg8810]

your explanation is really good and your information seems to be reliable. I would love to use your information on a paper for university. however your "reliable sources" as you call them in your account discreption dont list where you found the information. (at least I didnt see it) You would help me out a lot if you could maybe give me your sources. Thank you in advance. Keep up the good and interesting videos ;)

[@freddiepage6162]

Great video series Kathy!

[@Kathy_Loves_Physics]

Thanks Freddie

[@PoetryETrain]

Great video subscribed.

[@videolabguy]

I find your videos penetrating and illuminating!

[@Kathy_Loves_Physics]

Thanks

[@yasincelik3630]

Pretty informative, thanks a lot.

[@Kathy_Loves_Physics]

So glad you liked it, feel free to share

[@colombianflag717]

Great video.

[@Kathy_Loves_Physics]

Colombian flag glad you liked it.

[@saifearmansamnan9945]

Great videos.❤❤❤

[@Kathy_Loves_Physics]

Glad you liked it.

[@jimimaze]

I like the new mic!

[@h2energynow]

Tube had an opening in end and yet was a vacuum, or connected up to a machine that would create a vacuum. Didn't this cause a problem?

[@TheLewisLegend]

William Morgan discovered them 110 years before in 1785

[@dosomething3]

cathy - tell us about your journey. how did you learn all of this??😮😮😮😮❤❤❤😊😊😊

[@dosomething3]

1:22 “can be moved with a magnet 🧲 “ but why not with an electric ⚡️ source????😮😮😮😮😮

[@dosomething3]

if the cathode is losing electrons - would it not run out of them? 😮😮😮

[@dosomething3]

can i use an incandescent light bulb 💡 to create an electron beam? 😮😮😮

[@williamsoriano4557]

I have a medallion of w,c, roentgen 1895 -1995 do any one know its value?many tnx

[@NormReitzel]

"Hold up varioua items" ... Probably not an electric hand dill thouh.

[@gideonsikk8733]

Aww brutus

[@gerardkuipers4164]

I over this

[@sciencetimes6181]

Go fast

[@richaarrd1]

You said "develop the film" when you meant "expose the film" ... just sayin'

[@alammd.samsul8424]

mota moti biswas kora jai....90%....with love amd.

[@wiltonsmith3397]

Handcuffs…

[@DD-su2qq]

Sorry but Ivan Puluj discovered xray....

[@YouScroob]

I've wondered why there is no mention of him in this series.

[@MoveAhead101]

Johann Puluj admitted that Röntgen was first.
