AI Thread Summary
The discussion centers on the quantization of energy as demonstrated by the photoelectric effect, where photons are shown to have discrete energy levels. Participants emphasize the need for experimental evidence to support the claim that energy is emitted in quantized bundles. The significance of the photoelectric effect is highlighted as a key example of this phenomenon. The conversation also references a major paper published in 1905 that contributed to this understanding, hinting at Albert Einstein's pivotal role in the discovery. Overall, the thread underscores the importance of experimental results in confirming the quantized nature of energy.

Its an answer that I'm not 100% sure of.


was asked to show experimental results that require the emission of energy is quantized.



The photoelectric effect is an example. In the photoelectric effect, energy bundles (photons) are abserved to have a definite size (quantized).

You'd probably want to elaborate on that a lot more.
 
Yes, the photo-electric effect is a good example. Now, what exactly was it about the results of that experiment that prove energy comes in bundles?

(And who wrote the major paper on this? Hint: he wrote it in 1905, 100 years ago along with three other important papers that year.)

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'
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...
