Modern Physics 69- The particle behavior of light is proven by the photoelectric effect. 70- A photon is a particle of light {wave packet}. 71- Large objects have very short wavelengths when moving and thus can not be observed behaving as a wave. (DeBroglie Waves) 72-All electromagnetic waves originate from accelerating charged particles. 73- The frequency of a light wave determines its energy (E = hf). 74- The lowest energy state of a atom is called the ground state. 75- Increasing light frequency increases the kinetic energy of the emitted photo-electrons. 76- As the threshold frequency increase for a photo-cell (photo emissive material) the work function also increases. 77- Increasing light intensity increases the number of emitted photo-electrons but not their KE. |
