Albert and the Photoelectric Effect

AI Thread Summary
Einstein proposed the theory of the Photoelectric Effect in 1905, predicting how photons interact with metal surfaces. His work laid the foundation for understanding this phenomenon, but he did not conduct the experiments himself. Robert Millikan later confirmed Einstein's predictions through his own experiments about a decade later. The discussion highlights the distinction between theoretical and experimental physics, noting that Einstein focused more on theory. Resources for understanding Einstein's experiment are sought, emphasizing the need for clear explanations of the concept.

Homework Statement



My question isn't about a specific problem, but I was wondering if anyone had a good website that explicitly explains Einstein's experiment for the Photoelectric Effect. I've had trouble finding what he did. The only procedures that I've come across are those of proving he was right.


Any help is appreciated.
 
Physics news on Phys.org
I believe Einstein just predicted it in 1905 and Millikan proved it 10 or some odd years later. He was a relatively smart guy or something.
 
Einstein didn't carry out any experiment. He merely proposed what happens when a photon hits the surface of a metal plate.

Milikan's experiment confirmed Einstein's prediction.

Einstein is a theoretical physicists... And as far as I know, this guy don't really like the experimental side of Physics.
 
Thanks so much
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
