How does Cerenkov radiation work?

The behavior of matter can constantly amaze people, especially when extreme conditions are involved. In this video, Fermilab’s Dr. Don Lincoln describes what happens when a charged particle travels through a transparent material faster than light travels through that same material. When that happens, blue and violet light is emitted. This light is called Cerenkov light. This video tells you everything you need to know.

So it's a Luminal boom? As opposed to a Sonic boom?

*In a video about radiation*
"On the THIRD HAND..."
Hahahah i see what you did there

[DurinSBane-zhhj]

It's spelled both Cherenkov and Cerenkov until you turn the page and read it

[ferretappreciator]

As a not linguist, I'd like to say that Cerenkov is probably the worst way you could spell it in English

[WhitefirePL]

So basically this is the sonic boom effect, except it's not sonic :) So cool! Thanks. (EDIT: Oh yes, as it happens I am a linguist, I would probably prefer Cherenkov, not that it matters :)))

[SunriseFestival]

Completely normal effect, can happen with minimum radiation

[CsendesMark]

Longish video?
Dr Don, please don't give in for the short attention span people - and try to do more longer videos like this,
Thank You!

Grapheme "č" is used in Slovak, Slovene and Czech alphabet and is pronounced "tʃ" like "ch" in "choke". Черенков = Čerenkov = Cherenkov

Thanks for using my video in that last demonstration. Would really have appreciated a mention that it is shot at the Penn State Breazeale Nuclear Reactor.

Cerenkov light is like a subatomic sonic boom, but with light?

[АнатолийПархоменко-мб]

Real is Cherenkov. Because if it's Cherenkov then it's sound more like Черенков. If it's Cerenkov then sound like Церенков or Серенков these is not correct i think 🤔 i don't have good English knowledge. What i know is ch - ч, sh - ш, sch - щ, zh - ж.

[rkingstonkoser]

so it’s possible to travel faster than light but not faster than light in a vacuum, i think i get it now

[RuslanLagashkin]

As a Russian I can confirm Cherenkóv's name starts with the same sound as the word "chair" does. Cherenkóv.

After I watch Dr Lincoln's videos, I almost feel like I understand modern physics. Thanks for posting these videos!

As a kid my dad took me into the small research reactor at Cornell University to see the "blue light" at the bottom of a deep pool. Very cool to see! I was looking right at a nuclear reactor core with no protection but for the water, and seeing the radiation, sort of.

[TheDsasadsad]

Thank you.
I watched several long lectures about neutrinos and their detection and I only here got perfect explanation how this type of neutrino's detectors work.
And thank you for the detailed explanation of surname pronunciation. I as a russian myself greatly appreciate it.

[komsomolac]

Excellent video!

By the way, the letter "Č" is an actual letter in many of the Slavic languages that use the Latin script (for example, in Serbian language which uses both the Latin and the Cyrillic scripts). It's the same letter as the letter "Ч" in the Cyrillic script and it is pronounced - I am sure you have already guessed - as "CH" in English language.

[Landrar]

She was totally the bomb...

I just got vaporized by that bomb of a dad joke. 😂

[baruchben-david]

So do physics books have Capters?
The English representation of the Cyrillic 'ч' is 'ch'. Sometimes, you may find it represented as 'tch' as in 'Tchaikovsky'.
The physics books are simply wrong.

Fermilab videos with Dr. Lincoln are the best Fermilab videos.
