  • @TheCreampi3
    @TheCreampi3 3 роки тому +1

    Hi! Thanks, great video! I have a question though. The curcuit you illustrated at 2:33, why did you change the poles? I guess it works both ways, but wouldn't the energy threshhold for the electrons to be jumping over to the other metal plate be much lower before you changed the poles? I mean that it would be an electric field between the two poles.
    Does your explanation say that the electrons travel in the same direction as the current, if the photoelectric effect is "strong enough"?
    Best regards

    Given that you have frequency a and b and that a and b are greater than the threshold frequency and b is greater than a. If you read current x on the ampmeter with freq a, what will(or will not) happen with the current when you switch the incoming light to freq b? Intensity is to remain constant, i.e the machine that’s generating the photons is always running on say 10W=10J/s with both freq a and b. (assume straight line photon beam)

  • @tolgakaya7377
    @tolgakaya7377 2 роки тому

    Does that have to do with something that the surface area of the plate and the distance between the plates. Maybe the wave is in evanescent below that cutoff freq. Can’t the cutoff freq(f0) change under no circumstances? Maybe we should look from the parallel plate waveguide perspective in some sort such as only higher order modes are capable of photoelectric effect.
    But mainly I would want to know what determines f0
