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

Dude nice video you were born to teach, liked and subbed
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!!
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
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.
Thank you, very easy to understand and well drawn out!
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
I am so glad you did this! thank you for the simplicity!
thank you! this video helped me to have a clear idea about the basis of the photoelectric effect
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
Thank you so much mate.
Love the way you present .
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

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...!!
single handedly saving my physics exams, thank you sm
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.
Thanks for the amazing video! It really helped me with my assignment.
Thanku so much ur videos are make all the complicated areas seem simple and easy to remember
Was really struggling with this topic, I understand it so much better now :)
Thank you so much for this video! It was so helpful.
You're amazing at physics - keep up the good work and keep bringing the content
This was SO HELPFUL! THANKS A LOT!
thank you that was a really good clear and concise video. it is a great help in revising the topic.
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, very easy to follow
Very helpful! Thank you so much!
thanks so much, this was the only video that made sence, now i finally understand it.
This was soo helpful, in under 10 mins !!!I feel ready for my exam tomorrow now😂
Thanks man, this topic was confusing asf but u explained it clearly. subscribed and liked.
Great explanation! simple and clear. Thanks :-)
Thanks!! Really helpful
Thank you very much sir ! Best wishes from Sri Lanka 🇱🇰
Thank you so much for your vidz man!
Very well done. Thank you.
Omg i love this topic u explained it so well!
Kudos to you mate. Legit saved me by the minute.
Thank you for this very nicely explained
Amazing videos, keep up the good work.
Awesome! Thank you!
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
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?
You made this theory hit right into my brain sir......without any dought....Thankyou very much....
I was ready to get Zero on my report on this chapter but you just changed my mind, thank you so much 🥰 🥰
Thanks for this fabulous lecture
this was very helpful, thanks!!
Awesome explanation!
Thank you, that was very helpful
thank you so much you made it much easier
this is so helpful! thank you
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 :'-)
Great explanation!
Thanks man you helped a ton!
Super good explanation!
Great explanation 💛
This was incredible thank you
thank you so so so so much!!!!
You are very good at what you do

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!
Wow that is very nice explanation of yours.
Great explanation
Really good explanation.
Amazing polarity flip at 3:01.
greatest teacher ever to step on earth
Insanely good video man
You're good at explaining
Hey! Awesome video but I was just wondering if these videos fit the specification for the AQA or the Edexcel course
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.
Amazing . Thanks
Great video.
Thank you!
Thank you so much
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!
Great video!
Great Video!
Thank u so much . I absolutely adore u
Great video
Just great , Thanks a lot :))
Amazing vid was realy helpfull
Thank you sir.
Thanks😊
great videos
This was lifesaving
Very useful thankyou
thank you so much
great video!
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
This video is amazing
you saved me big time!!!
Good job
