    Photoelectric Effect - Intensity in Phototube

    Anyone enlighten me about how a low intensity relates to the RC time constant? :frown:

    Photoelectric Effect - Intensity in Phototube

    Thanks for that explanation. How would i go more into depth and integrate "time-constant" into the explanation? Because in the experiment we were initially ask to find out the detector's time constant, by timing it until the voltage dropped to e^-1 of the initial E. and i figured somehow...

    Photoelectric Effect - Intensity in Phototube

    We have been doing some experiments using a mercury light source and filters for each wavelenght and a Detector Box (phototube) to measure the output voltage, to investigate planks constant, stopping voltage, intensity's effect... the typical - "energy is quantised" idea. :zzz: There is one...

    Polarization Reflection question

    A thin film of ethyl alcohol (n=1.36) is spread on a flat glass plate and illuminated with white light. When illuminated and viewed from directly above, it shows a coloured pattern in reflection. If the only visible light reflected by a certain region of the film is yellow (lambda=560nm), how...

    How Thick is the Ethyl Alcohol Film for Yellow Light Reflection?

    A thine file of ethyl alcohol (n=1.36) is spread on a flat glass plate and illuminated with white light. When illuminated and viewd from directly above, it shows a coloured pattern in reflection. If the only visible light reflected by a certain region of the film is yellow (lambda=560nm), how...
