You explained this thing in 9 minutes and my teacher couldn't do it in years! 😂 thnx M8
My teacher is awensome but we are in Italy and this lesson with his English was impossible to understand
tru lol
@@alanwong9508 took me 4 noob
@@alessandromarchiori38 perche guardi video in inglese allora? 🤣🤣
@@gabriellita7236 con his intendevo l’inglese del mio professore. La lezione era in inglese e nella verifica la risposta sarebbe stata da dare in inglese
Oh my gosh. In under 10 minutes you have explained more than my teacher has done in about 12 lessons, and you made it even more understandable. Thank you so much
你最好别踏足重庆
Someone in my class showed me the textbook about this topic and I was sitting there like "what???" but you made it so easy to understand, keep doing what your doing!!
Dude nice video you were born to teach, liked and subbed
Who here has exams in a few weeks??? ;) good luck lads
Tom de Whalley my exam is on upcoming Tuesday 😫 good luck mate
RossBruh SAME good luck!
Tom de Whalley thank you mate you too!!
ive exam in 12 hours
Asim Iftikhar best of luck mate
I'm new to a-level physics and for a topic I thought was difficult you explained it to me clearly in under 10 minutes. Thank you
broooo, you’re the man 👍🏻👍🏻👍🏻👍🏻
my teacher waffled on and on for many lessons, it would’ve been much easier if he just showed us this video. I subbed and Liked

Really useful video. Thanks for guiding us through the whole photoelectric experiment process (including showing us how the equation was formed)!
Thank you so much! I'm in quarantine rn and I honestly thought I wouldn't understand this topic before this video.
This video deserves an award. I don’t think anyone else could have explained that better.
I liked it at 0:01, as every vídeo of yours is amazing 😉 Thank you so much, I am preparing for PAT and this is sooo helpful. It’s really calming to discover you have a video on what I need to learn 😁
Please keep making these videos! Your explanation was crystal clear and very easy to understand. Liked and subscribed :D
Thank you! I know this video is 5 year old, but it's still coming in handy. Got a physics exam in 2 and a half weeks and this is great consolidation on the photoelectric effect :)
Amazing teacher. You don't have any idea how much your videos are helping sir. Thanks a billion fold
Great video. Thank you so much. I have a test coming up shortly and I needed a full explanation this has been amazing! Do you do maths videos as well?
Thank you, very easy to understand and well drawn out!
I am so glad you did this! thank you for the simplicity!
awesome job...thee BEST i have seen...very well explained in simple, and clear demonstration..thank you SO much..now i can REALLY enjoy all my higher mathematics books...!!
thank you! this video helped me to have a clear idea about the basis of the photoelectric effect
Really helpful, concise, very understandable. Thank you very much for this lesson. You are even better than the PhD teacher of my college !!! in terms of explanation.
Thank you so much mate.
Love the way you present .
Hi! Thanks, great video! I have a question though. The curcuit you illustrated at 2:33, why did you change the poles? I guess it works both ways, but wouldn't the energy threshhold for the electrons to be jumping over to the other metal plate be much lower before you changed the poles? I mean that it would be an electric field between the two poles.
Does your explanation say that the electrons travel in the same direction as the current, if the photoelectric effect is "strong enough"?
Best regards
You're amazing at physics - keep up the good work and keep bringing the content
Was really struggling with this topic, I understand it so much better now :)
Thanks for the amazing video! It really helped me with my assignment.
single handedly saving my physics exams, thank you sm
Thank you so much for this video! It was so helpful.
This was soo helpful, in under 10 mins !!!I feel ready for my exam tomorrow now😂
Thanku so much ur videos are make all the complicated areas seem simple and easy to remember
Your videos are amazing! I wish my teacher could explain these concepts this easily
OHMYGOD DUDE!! i love you!! You have no idea how easy and wonderful that was. It's gonna make my exam so much easier for me!! Thank you.
Great explanation! simple and clear. Thanks :-)
This was SO HELPFUL! THANKS A LOT!
Thanks man, this topic was confusing asf but u explained it clearly. subscribed and liked.
thank you that was a really good clear and concise video. it is a great help in revising the topic.
Thank you very much sir ! Best wishes from Sri Lanka 🇱🇰
You made this theory hit right into my brain sir......without any dought....Thankyou very much....
Amazing videos, keep up the good work.
thanks so much, this was the only video that made sence, now i finally understand it.
Omg i love this topic u explained it so well!
Thanks!! Really helpful
As someone who recently graduated with their degree in philosophy, thank you for making it bite sized and understandable
Why are you watching a level physics if you have a degree in philosophy?
@@euclid7912 why try and limit what you can learn?
@@lakewoodbball I'm not... I didn't say you couldn't. I just asked why..
@@lakewoodbball No problem man. You too.
body decided to get the flu during the week so i missed the lessons where my teacher explained this stuff. this really helped me, thank you! will come back for my end of years :'-)
Thank you so much for your vidz man!
Given that you have frequency a and b and that a and b are greater than the threshold frequency and b is greater than a. If you read current x on the ampmeter with freq a, what will(or will not) happen with the current when you switch the incoming light to freq b? Intensity is to remain constant, i.e the machine that’s generating the photons is always running on say 10W=10J/s with both freq a and b. (assume straight line photon beam)
Thanks for the great video!
Very helpful! Thank you so much!
Kudos to you mate. Legit saved me by the minute.
I was ready to get Zero on my report on this chapter but you just changed my mind, thank you so much 🥰 🥰
Hey! Awesome video but I was just wondering if these videos fit the specification for the AQA or the Edexcel course
Thank you for this very nicely explained
still helping students like me in 2023!! awesome stuff brother. Zoing!!
Zoing indeed.
bro i looked at my textbook and it was complete waffle while i looked at ur vid and everything fell into pieces thank you so much
Very well done. Thank you.
Awesome explanation!
Amazing polarity flip at 3:01.
Thanks for this fabulous lecture
Super good explanation!
this was very helpful, thanks!!
Awesome! Thank you!
You are very good at what you do
IT IS A CELL NOT A BATTERY!!! REEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
gudmeme
I hope your safe space is doing the trick.
Great explanation 💛
Great explanation!
Insanely good video man
get me a sharpie
Wow that is very nice explanation of yours.
This was incredible thank you
this is so helpful! thank you
thank you so so so so much!!!!
hi im a student from iran i never didnt underestand this subject until i saw your video that helped me a lot so thanks alot :)))))))))))))
Great video man!
Really good explanation.
thank you so much you made it much easier
oh man this is so helpful you are great thank you
Great videos, I have a2 physics paper 2 tomorrow, hopefully thanks to your vids it goes better than paper 1 :/
Jon Snerr do we need to know this for tomorrow?
Yes, but you should already know it from AS.
Jon Snerr yeah dw i know everything
I am so screwed for paper 3
Jon Snerr yeah same especially the experiment errors etc bit
Great explanation
I have a quick question: why does the light ,in milikan’s experiment, have to “roughly monochromatic”? when in the photoelectric effect experiment it doesn’t
You're good at explaining
So useful, now I understand it all
For the stopping potential, when calculating energy why don't we need to consider the work function of the metal?
greatest teacher ever to step on earth
Hi, I’m a bit confused as why the gradient of the line has to be Planck constant, is it something i should know the reason to or just something I need to remember
Thank you! ❤️
Thanks for explaining the practical when we can't do it in school. One thing I noticed, however, was that you called a cell a battery at 3:23!
Seriously, it really doesn't matter. Please stop.
Lmao
as per the graph, the particle wont be leaving at all and if it leaves it will be having a basic kinetic energy? The electron will leave with a basic speed or more but cant leave below a fixed velocity?
Thank u so much . I absolutely adore u
great video!!
will you be doing electricity any time soon ?
+Hasan Halim Probably next week :)
Great video.
Amazing vid was realy helpfull
How does this link with the golden leaf experiment? Cheers
If have a question. I heard that photons are changed into heir path by black holes but shouldn't this be impossible as they have zero mass?
Does that have to do with something that the surface area of the plate and the distance between the plates. Maybe the wave is in evanescent below that cutoff freq. Can’t the cutoff freq(f0) change under no circumstances? Maybe we should look from the parallel plate waveguide perspective in some sort such as only higher order modes are capable of photoelectric effect.
But mainly I would want to know what determines f0
Great video!
Great Video!
Amazing . Thanks
Just great , Thanks a lot :))
Thank you so much
Thank you!
4:12 will increasing the frequency of light increase the current in the circuit?
This was lifesaving
