Photoelectric effect experiment

Hi there,

I have this problem with this photoelectric effect experiment.

In the image of my attachment particulates will be ejected from C and move to D. The electric field(by A and B) will change the particulates trajectory to A, B or will not change this?

Thanks
Tony

PS: Sorry about my english.

Hi Tony! :smile:

(btw, we call them "particles" … "particulate" is usually an adjective :wink:)

the particles are negatively-charged electrons, so which way will they go? :smile:
 
the negatively charged photoelectrons will move towards the positively charged plate A as unlike charges attract each other.
 
I have a sneaking suspicion that cathode ray tubes are built with the deflection plates inside the glass for a good reason. What do you think?

Thread 'Schrödinger equation and classical wave equation'

Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Thread 'Is Maxwell's electromagnetism an effective (field) theory?'

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
