Capacitance: Charge stored on two parallel metal plates due to a potential difference between the plates. The capacitance is directly proportional to the Area of the plates and inversely proportional to the distance between the plates.
1 st Law of thermodynamics: Heat added to a system (gas) is equal to the work done by the gas plus its change in internal energy Work is done by the gas when the volume increases. Work is done on the gas when the volume decreases.
The Photoelectric Effect: Evidence for the particle theory of light. Photons incident on a metal eject electrons from the metal with a maximum kinetic energy that depends on the frequency (f) and work function of the metal ( ϕ )
The slope of the graph is planks constant and the y intercept is the work function. The x intercept is the threshold frequency
DeBroglie wavelength equation relates the wavelength to the momentum of a particle.
