wow very cool Lonnie. greetings from estonia 😜😜😜😜😜😜😜😜😜😜😜😜😜😜😜😜😜😜
Ответитьhow do photons travel through a glass vacuum light bulb? and then through the glass? if its filled with particles how does it not all get stuck in the glass and get stored there and make the object hotter? why does light travel through billions of particles that form a structure. I get it more if the structre is crystal, but what about if its glass and random arrangements? shoudlnt all glass look different? or maybe photons escape through because they are sooooooo small? idk can someone give me the why of why particles travel though glass?
ОтветитьThankuu sir...❤
ОтветитьWhat IS this? Einstein said light is quantized on the basis that only UVC (or thereabouts) could knock off electrons. This is saying the exact opposite! That lower frequency yellow light will generate some low energy "photelectrons", and green light some more with a higher energy, and visible blue light even more; seemingly contradicting the master! What am I missing here? Given that the meter was at full-scale deflection with white light, I suspect this is really just showing how red photons have lower energy than blue photons? If that's the case, then why is "photoelectric effect" in the title? No matter how intense a visible white light source is shone onto a negatively electrostatically charged metallic surface, the electrons are not "knocked off"; its only higher energy photons in the non visible UV range can dislodge the electrons; that's the whole point of the "photoelectric effect".

ОтветитьThanks Lani
ОтветитьThe meter is maxed when there is no color filter.
Does this mean that the raw un-filtered light has the highest energy to eject photoelectrons?
😍🥰😘
ОтветитьUniversity Level? Really???..... the meter shows the energy of the photons? How.??????
ОтветитьWhy does the multimeter return to 15 instead of 0?
Ответитьwhy is chemistry
Ответитьcool...!! greetings from india ❤
ОтветитьThank You sir
ОтветитьThanx
ОтветитьThank you ,good video
ОтветитьIt dod not help me too much but itzz cool and i liked this video, good work, i appriciate ur work☺
ОтветитьIt 'll be very useful if u let me know the experimental set up,metal plates used and vacuum conditions followed by etc.,I wish to perform this experiment, 'll u help me sir?
ОтветитьWhy white light show photoelectric effect
ОтветитьGood work
Ответить<3
ОтветитьAwesome...
Ответитьomg, that's soo cool! many thanks!
Ответитьwhy are blue photons the highest visible photos and not violet?
Ответитьwhy didn't the photoelectric effect take place before he placed the filter even though the same amount of blue and other wavelengths were present ?
Ответитьohhhh
Ответитьinteresting . tnx for the video . greetings from India
ОтветитьWhat about purple glass
ОтветитьI noticed the multimeter needle goes to 7 with the blue filter. Is that 7 volts?
ОтветитьWhat is a blue photon?
ОтветитьBoring!
Please show me all the equations and constants which are related to the photoelectric effect.
+Barnes David Sky is blue due to the scattering of light and this video was good but not that informative at all, i believe it should've shown the principle more fundamentally, like how the electrons are emitted when photons hit it and where is the receptor of those electrons but anyways..its cool
ОтветитьHà oi.
ОтветитьThank youuuu!!
Ответитьeven though i loved the video i am still a physics lover. so it wasnt that spectacular.
ОтветитьSo is that why the sky is blue?
Ответить... also, the experiment i describe explains why robots stop working in fukushima, so many electrons get knocked out that electronics fail. its the same photoelectric effect, just on steroids, with a really scary x-ray generator. But then, it would be unusual for a chemistry lab to have lead bricks and one inch thick lead glass and stuff for radiation safety and an x-ray generator at hand.
Ответитьif you think THATS cool... well, i studied physics, and one experiment they showed in lecture was a box of 3 centimeter thick lead glass box with an x-ray source, and some electrostatic experiments. They open the box, put charge on the electrostatic meters and experiments, close the box, and the electrostatic experiments are discharged instantly, in split seconds. styrofoam pieces sticking to the inside wall of a container drop, the needle hits zero, and so on. THAT was cool.
Ответитьso cool
