Sorry to be so offtopic but does someone know of a trick to log back into an instagram account? I was stupid forgot my account password. I love any assistance you can give me
@Angel Korbyn Thanks for your reply. I got to the site on google and I'm waiting for the hacking stuff now. Seems to take a while so I will get back to you later when my account password hopefully is recovered.
Great video....But I have a confusion....What if more than one photons collide with the same electron?? Does the kinetic energy of the electron increase then?? Obviously, It can't be. That's the whole point of photoelectric effect. But why not??
Then explain the color spectrum of light if it is only expressed through particles?- Did we not recognize that light is a mixture of wavelengths and particles when both Einstein AND Newton were awarded the Nobel prize after the original proposition?
I'm a biomedical sciences student. this year I have physics 1 & 2 and I'm really struggling since I'm more of a bio/chem girl. these videos make me see my theory from a different perspective, thank you so much!
Just wanted to say THANK YOU, this video has been absolutely spot on for what I need. I'm genuinely looking forward to checking out your other videos. Thanks once again.
I don't get it. If light can be described as a collection of photons, and the amount of energy in a photon is proportional to it's frequency, then how come the energy of an EM wave is suddenly independent of it's frequency? If light is an EM wave, and also a collection of photons, then the energy of this wave should increase with frequency, as does the energy of photons.
5:14 using particles to represent the energy. Not that that is incorrect, but why *would* it be incorrect to represent it with the crest and troughs of a wave?
2:15 how do we know if a metal releases electrons? Also what is blue light? I get it, the wavelength but how do you produce a shorter or longer. I would appreciate very much if someone were to help me.
In a photoelectric cell there is a collector. The electrons released by the metal reach the collector and are measured as a current that loops around the cell. The PhET site has a Photoelectric Effect simulation that shows this well. To get blue light we take white light and place a filter over it. This filter only allows blue light to pass through it.
Can you elaborate on "changing the amplitude of light"? I really don't know how to phrase the question better. Hopefully if you answer, I can respond and narrow down what I am driving at.
Are you referring to changing the INTENSITY of the light? If so, as the intensity of light is increased, there is a increased rate of photons hitting the metal. More incident photons means more electrons can be released (if the frequency is above the threshold frequency).
@@bredmond812 the intensity of the light is equivalent to the brightness of the light. If you increase the brightness then you have increased the intensity.
1:55 you just explained how classical theory still explains the photoelectric effect; increasing frequency increases the electron discharge. there was never any need to consider light as a particle to explain the effect. einstein was just losing his mind from lead-tainted food and water, and everybody just went along with him cuz he established himself as a genius. it's all malarky.
frequencies of light from de-excited electron energy states show which atom is being observed. measuring atomic spectrum has nothing to do with the cause of photoelectricity.
I'm confused. When you said "no need to consider light as a particle to explain this effect", do you mean that light doesn't exhibit particle behavior at all?
Best explanation of photoelectric effect I've seen so far out of about 5 videos. Thanks.

Dear friend,you're talented in explaining theories :) please continue we need teachers like you.

@Decker Hayden instablaster ;)

@Angel Korbyn It worked and I actually got access to my account again. I'm so happy!
Thank you so much you really help me out :D
@Decker Hayden happy to help :)
These have been in sync with my class and have been extremely helpful, thank you!
Ceebers You're very welcome!
@@BensChemVideos Amazing your video is 5 years old and i still find it very useful and obviously informative. Thanks a lot.
@@thealtruistmc5020 you're very welcome! Thank you for your kind words!
Best video i have ever seen explaining photoelectric effect 👍👍👍👍
wow, watched so many videos and by far you explained it the best! Thank you!
You're very welcome! Many thanks for watching and commenting! 😀

can a collision cause the photon wave to be excited which turns it into a particle... which than gives off an electron?
Bro, I love your vids. I use them on regular with my kiddos. Btw, I`m a science teacher.

Who came here from Mr Selva?
I'm curious...who is Mr. Selva?

Does the incidence angle affect which way electrons move?
You look like Jesse Eisenberg, also great video
Ah this explains why the charge leaks away on my van de graaff
where to find to your previous or upcoming videos?
Audio volume is very low.
Thanks! I wish there was a way to fix that in the UA-cam editor 😭
u are better than my docor in uni
Thank you for your kind words, and thanks for watching!
Literally PERFECT thank you so much

This is all kinda a bruh moment

Why do atomic emission spectra show spectral lines rather than a continuous spectrum?
frequencies of light from de-excited electron energy states show which atom is being observed. measuring atomic spectrum has nothing to do with the cause of photoelectricity.
I'm confused. When you said "no need to consider light as a particle to explain this effect", do you mean that light doesn't exhibit particle behavior at all?
particles are not made of electromagnetic waves. there might be a short pulse of a wave, but that doesn't make it a particle.
Does light exhibit particle behavior at all?
This was so helpful!!
Awesome! Thanks for watching 😀
Great explaination
Thank you for your kind words, and thanks for watching!
why do look like you've been formed from jesse eisenberg and idubbbz
we can use this photo electric effect to create unlimited energy
