Spectrum Demo: Continuous and Emission

Wish I could have had more teach like you when I was in school

Exactly what i needed!

You have very different perception of color. What you call purple is blue and what you call turcoise is lightblue. You was not even close

Thank you so much sir that's why i am subscribing you

SO thats how light sabers get their colour

I have hydrogen spectrum in my 12th grade curriculum. That is why I have come here to understand it well from india.

ماكوا طالب سادس

Ok This makes physics interesting again. For real, reading this in textbooks without images is so boring. IT IS A CRIME TO MAKE PHYSICS FEEL BOOOORING.
+Thanks a lot prof.

Use the fur to prevent burning flesh. Check.

So way back when, all Neon signs had that orange-red color?

Is the mercury a gas or a vapor suspended in the tube? Or is the liquid mercury glowing?

How can a bulb emmit continuum spectrum, if light is always transmitted via photons with quantified energy?

This looks like a piece of clear plastic, it's not. It's actually a piece of clear plastic...WITH LINES ON IT! !!!!!

And my professor just asked use to look at the diagram in the books...

Thank you sir the experiment cleared lots of my concept

Pay attention to the ionized hydrogen and when Professor is saying how it is important in observing Nebulae, i.e. dispersed ionized gas in space. Now, think for a while why do we still consider stars as balls of gas? They emit continuous spectrum of light which can't be produced by ionized hydrogen and nobody cares. They can't be made of gas. They must be liquid or solid. That's why they have no bloody clue why fusion facilities can't get an excess energy in the process of fusion reaction. They have no bloody clue what happens in stars. The proof is in front of you very eyes. Watch it again if you doubt it.

It´s amazing, the demostration help me in my studies!

cool stuff

Wow ! 👌 just loved it. Nothing can be more interesting than seeing, in real, a phenomenon 🤩 that one is asked to imagine or visualize & of course then memorize - the Indian way 😏

Thank you so much. Can you give us the reference of your lights? We're can we get them? I'm physics teacher in France!

The coolest explanation

What's the name of those bulbs? Thanks!

Thank you sir , I am currently studying this topic , this helped a lot🙏🙏

Who is for jee prep here..

Amazing colour

The violet line in hydrogen spectra is just like lightsaber of mace windu

Sir why voltage was given to gasses

Wowwww wonderfull physics!❤❤❤

Thank u so much Professor ....
I'd watched tons of videos but not able to understand but now it's crystal clear...♥️

this is so beautiful thanks for sharing it😍🤩

Thanks you for this demonstration.🙏

Hello, I am a student from Iraq

America has win zat ho oqat ho

So he can see in darkness

EXCELLENT
THANKS

that's why we love to learn from abroad teachers.

Sir,is the spectrul line width is dependent on temperature of the given gas?

Such pretty lightsabers haha. So awesome. Thanks for this demonstration sir

Sir, Tons of Respect from India, for the clear demo 🙏

Great video

Amazing demonstration! Where can we find this big, diffraction grating?

ඞ

Why is red light most deviated? Shouldn't it be the least deviated one?

4: 48 spectrum looks like pillar

Excellent demonstration! Thank you for sharing.

what is the limitation of this experiment?

Even our physics teacher showed THIS video to show us what spectrum is. Thank you for this wonderful video

colleges should show this experiments to visualise students

Here Emission spectrum means type of Atomic or line spectrum... Am i right? Plz tell me ... I've a lio confusion
