blackbody radiation
a theoretical (ideal) model that absorbs all radiation falling on it - a “perfect” absorber or emitter
2
New cards
E = nhv
Planck’s mathematical expression to describe the phenomenon of blackbody radiation by theorizing that energy is quantized
3
New cards
classical mechanics prediction
if you increase the frequency of light shined on a metal, the metal will eject more and more electrons. there is no relationship between the light and the kinetic energy of electrons
4
New cards
photoelectric effect
only electromagnetic radiation with v >= v0 could eject electrons from the surface, even if the brightness is increased
5
New cards
photons
packets of light
6
New cards
why is light a particle
photons are discrete packets of energy
