Cathode Ray Tube

[spunky1776]

haha this guy sounds like Nicholas Cage!

[kos00021]

i'm 12 years old

[AllAboutMac27]

OMG! That literally was better teaching than my teacher will give me all year! He told us to go on a website to find out what this was all about :(

[zwinzstarr]

Thanks to you I'm going to get full marks in Physics :D

[Jameslikespudding]

omg this looks just like my science room o.O and the teacher is wearing the same clothing my science teacher would wear XD

[shiza223]

Simply great explanation!

[aFluffyMongoose]

i enjoy delicious taste

[seethingnuclearchaos]

Moving electrical charges DO NOT bend towards or away from the poles of a magnet. Magnetic poles are north and south and are most definitively NOT potive and negative. The paths of moving charges bend perpendicular to the magnetic field lines according to the right-hand rule. The video explanation of what is going on is, therefore, completely incorrect.

[MegaShrut]

can u show the details and make the expeiment real time as done in lab by j j thompson

[andretatontos]

Not close enough. I want to see it with my own eyes :*(

[narendrakumar57]

wow ser thanks of to you i really become thanks to you

[perjanan]

so, electrons don´t exist, how the fuck do we got that conclution?

[jvemPiRe14]

@perjanan rip electrons

[MrPacmanpunch]

Lmao he is not even wearing a lead vest to deflect the x rays away from his genitles i guaruntee this dude had cancer now.

[hunchbak01]

If only that guy was my chem teacher

[jvrcb17]

thumbs up if this guy is better than your professor.

[Djshoorav]

damn i wish that was my chemistry teacher

[hardstyle905]

Great teacher and great video.

[shabboplow]

its being... repelled. lol teacher talk, they always stop to let the kids answer and they dont know it lolz

[metro2089]

no x rays here, thats why they use the florescent material so you can see them without using extremely high potential .

[chik5935]

awesome thnxxx

[timmy8911]

this creates x-rays when it is used so it is quite bad for you

[Herman9419]

@timmy8911

You're quite wrong on this one, I fear. An x-ray tube uses an anode made of wolfram (W), which absorbs the kinetic energy of the electrons and eventually transmits part of this energy in the form of x-rays. The tube the teacher in this video is using is a normal accelerator, just like the ones in the old televisions and in oscilloscopes.

[jrv01007]

I believe there is an extremely small amount of gas under low pressure in the tube, not "no gas". The reason why there is a beam, is because there is a small amount of gas with electrons that are fluorescing, right?

[Herman9419]

@jrv01007

I agree with you, there must be some gas under low pressure in the tube. Otherwise you wouldn't see the beam of electrons until they'd hit the wall of the tube, because they can't interact with particles when there is a vacuum in the tube. Electrons are mostly made visible with hydrogen under low pressure. The color of the beam seems to point to hydrogen as well, for it has a major spectral line at 486 nanometers, which is the wavelength of some blue- greenish color.

[giakful]

I would love to have this object. where can I buy it?

[demonscar24]

best explanation i have seen so far thnx

[GrantLogan2]

isnt this kinda hazardous to this guy?

[DescendantsOfEnoch]

Look into the dendera light...

[shAdOwstAlkEr945]

thumbs up if your chemistry teacher brought you here

[O0oSorousho0O]

@shAdOwstAlkEr945 Yea are you from UOIT?

[MrPacmanpunch]

@shAdOwstAlkEr945 nope my physics teacher did.

[AllAboutMac27]

@shAdOwstAlkEr945 :( I wish my chemistry teacher was that nice.

[bigwoolleypenguin]

zinc sulphide

[puiyan520]

Superb! Understood. Thanks alot! :D

[Ghuntu1]

Is the tube coated with Zinc Sulphide?

[arindam0071]

@Ghuntu1 yes which glows on when particles fall on it

[warnaka123]

thanks.......i've understand very well about this...

[duythuy2007]

perfect!! I finally understand it! thank you!

[vikashdilip]

that is so easy when u started explaining

[DeMagnete]

That was a great explanation. Thank You

[Petiahappy]

Perfect explanation!

[kitzayitzay]

nice work.....heaps of help....appreciated

[darthisaiah]

I feel like crap watching these kids in highschool learning something i havent even learned in college yet.

[bob505470]

the chemial scree is phosphorus

[erjohnson227]

How did he not know that lol. He is an honors chemistry teacher, and yet he doesn't know what is inside it.

[ausj02]

thank you!

[BelgiumUNRep]

this packet IS WASTING MY LIFE AWAY MS SOMMERS

[falconseye97]

i can relate lol

[TheTomislav]

SAME HERE

[Badboyz9472]

Very informant, thanks

[2dendsfdert]

wow!!!

amazing!!

[swenzih]

Correct me if I'm wrong here, but Quark is the smallest thing?

By the way, seen alot of your videos and I'm jealous of your students! Would love to be in your class, only problem is that I live in Sweden. But keep the videos coming! really love them.

[prangfunpro]

woot woot hummers honors chemistry class!
