Not going to lie, you make me want to keep on revising for my physics exams.

I don't usually leave comments but this is a really well-produced video, the physics knowledge is also more in-depth than most of the videos I've seen on this topic. Suprised this channel only has 14k subs.

If the world had more teachers like you teaching in our schools, then we'd all be noble prize winners

[aaronlang]

Why is physics so satisfying? Every time I wonder about something with physics, there's a perfect explanation and that explanation just clicks inside my mind.

[littledemon]

Your a really good teacher, i actually ended watching the whole video even though the answer i wanted was already answered.

You are the best teacher ever. My physics teacher at school spent a couple weeks on this I didn't get it at all, your 13 minute video on 2x speed (bit rushed for time!) cleared it all up. THANK YOU! omg!!

[ileggaless]

my teacher literally forgot to teach me this and my qualifying exams are in a week.... And you just taught me at least a week's worth of lessons in almost 14 minutes. Your amazing. Keep it up.

This has to be the best explanation of this particular topic I ever heard, ❤️

[Elitea]

Me after teacher explained this: *de excitation*
Me after seeing this video : *excitation*

[hamsalexus]

not exaggerating.... but these videos made me understand things the my teacher take 2 hrs to explain and usually takes 2 to 3 classes to finish... in just 10 to 15 mins.... these are life saviour... I love physics ....and my teacher is a good teacher and I mostly understand him but sometimes it takes my teacher ages and sometimes it flies over my head a few times I thought of quitting physics.. thank you for making my life

[liamabbott]

This is an incredible explanation. Thank you so much. You’re a legend

[진유-lp]

You are my life Your videos are absolutely helpful for students like me who study a level independently.

[PreeshaPrabhath]

This video is incredible. Understood a concept I’ve been struggling with for a long time in a matter of five minutes. This channel is brilliant

[fullsendmountainbiker]

Oh my god I’m watching this at 10 at night before my actual A level physics exam and I finally fully understand this topic thank you! 😅

[gabriellita]

Wow, you are an amazing teacher. Not only do you explain well you also make us students feel somewhat engaged as it is easy to understand the logic behind what you teach. Keep working hard and I hope you make a lot more subscribers.

[maazabrahani]

thank you so much for making these videos. they are very helpful. they make physics so easy and a fun subject. thank you once again. love from Zimbabwe

I have my first paper for phsyics today. Your videos have saved me !

[faip]

At 6:18, is there anything that prompts the photon to be remitted for the the electron to go down an energy level or is it a random process?

Also, thanks for the video! It's clearing up a lot of small things that I couldn't quite place together.

[MrChai]

At 6:42 How about if incoming photon have energy at 6 eV ?
Do the electron at ground state excite to 5 eV ?
And how about remaining energy 1 eV where it's gone? Do they transform to another form of energy ? And what the remaining 1 eV energy will be?
Thank you for your clear and nice presentation.

[shimaasalah]

You are a legend!
finally, I found someone who explains physics in-depth and it makes sense, Thanks a lot.
I will pray for you to reach millions soon.
