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
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!!
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 :)
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
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 😁
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 :'-)
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...!!
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.
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
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!
you did. the quanta itself is the wave its the spin properties that drive the wave function. also the capacitance of electrons is spectrum dependant. 8:1 infrared photons to visible spectrum and this is the reason its colour not carbon for climate change
I think that an electron is a positively charged ion, which should be emitted from the metal plate(cathode) towards the collector (Anode). Also, I think that negatively charged ions are attracted to positively charged ions. Why are the electrons emitted from the anode instead of from the cathode which emits electrons in your diagram? Also, do we have an electron that is a positively charged ion? I need clarifications, sir. Thank you.
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
Waves overlap with each other when you add multiple inphase waves. That should give more energy to electron but that doesn't happen in photoelectric effect.
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?
You explained this thing in 9 minutes and my teacher couldn't do it in years! 😂 thnx M8

Dude nice video you were born to teach, liked and subbed
Wow, man, I am floored. This is literally THE MOST INSIGHTFUL explanation of this effect I have ever heard. PLEASE MAKE MORE VIDEOS!!
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
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
This video deserves an award. I don’t think anyone else could have explained that better.
Thank you so much! I'm in quarantine rn and I honestly thought I wouldn't understand this topic before this video.
single handedly saving my physics exams, thank you sm

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?

Really useful video. Thanks for guiding us through the whole photoelectric experiment process (including showing us how the equation was formed)!

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
Was really struggling with this topic, I understand it so much better now :)
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

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 explanation, very easy to follow
Thank you, very easy to understand and well drawn out!
This was SO HELPFUL! THANKS A LOT!
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
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.
Thanku so much ur videos are make all the complicated areas seem simple and easy to remember
Kudos to you mate. Legit saved me by the minute.
Thanks man, this topic was confusing asf but u explained it clearly. subscribed and liked.
For the stopping potential, when calculating energy why don't we need to consider the work function of the metal?
I hope I’ll be doing A level physics in September. This looks really interesting
So will I where are you from?

Thank you for this very nicely explained
"Incidentally" See what you did there
This was soo helpful, in under 10 mins !!!I feel ready for my exam tomorrow now😂
shouldn't the cell be the other way round if you are going by conventional current as then it will oppose the direction of the photoelectron
Really good explanation.
Thanks for this fabulous lecture
Thanks for the amazing video! It really helped me with my assignment.
You are very good at what you do
Super good explanation!
2 months my teacher rambled on and on abt this, and now I know what it is in 9 mins 😭
Wow that is very nice explanation of yours.
You're amazing at physics - keep up the good work and keep bringing the content
So useful, now I understand it all

better more explanation than my teacher ever did it
Thanks!! Really helpful
Thank you so much for this video! It was so helpful.
thanks so much, this was the only video that made sence, now i finally understand it.
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?
Great explanation
get me a sharpie
why chigga
This was lifesaving
They travel as a wave but are electrons
Reaction of an action, meaning that light is a variable not a prime.
😐
Isn't this how the EM drive works? Electron mass for propuldion?
Trevor Thieme yes you got it. Propuldion is directly proportional to the frequency of the photon.
You would make a very good Udemy course with this material!
Thanks man you helped a ton!

How do you prove (experimental or theoretical ) that photons have no mass?
🤷
Waves can also come in discrete packages of energy depending on how the medium is vibrated.
Waves overlap with each other when you add multiple inphase waves. That should give more energy to electron but that doesn't happen in photoelectric effect.
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?
Very well done. Thank you.
Nice video, one question though
Where does the work function energy go?
releasing the electron from the metal
this was very helpful, thanks!!
thank you so so so so much!!!!
