Photoelectric effect compared to the particle theory

AI Thread Summary
The photoelectric effect demonstrates that if radiation frequency is below a specific threshold, no photoelectrons are emitted, regardless of intensity, which supports the particle theory of light. This is because, according to the particle theory, each photon must possess sufficient energy to overcome the work function of the material to release electrons. In contrast, wave theory would suggest that increasing intensity should eventually produce photoelectrons, regardless of frequency. The relationship between photon energy and frequency is crucial, as higher frequency photons carry more energy. Understanding this relationship clarifies why the particle theory aligns better with the observed phenomena in the photoelectric effect.

Homework Statement



in the photoelectric effect, if the frequency of the radiation is below a certain cutoff frequency, no photoelectrons are produced no matter how intense the radiation is. Why does this fact favor the particle theory over the wave theory?

Homework Equations





The Attempt at a Solution


I know that the particle theory was that all light was made up of particles. I also know that the photoelectric effect has photoelectrons emitted under correct conditions. What I do not understand is how to use both of those concepts to explain the answer to this queston.



Help please! =]

In the particle theory, each photon must have enough energy to overcome the work function of the material containing the electrons.

Do you know how photon energy and frequency are related?
 

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'

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...
