PHYS 1010 Lecture Notes - Lecture 24: Louis De Broglie, Werner Heisenberg, Radiant Energy
Document Summary
Composed of atoms with positive nuclei and negative electrons. Composed of atoms with negative nuclei and positive electrons (positrons) Both matter and antimatter cannot exist in our environment. Have the same mass as an electron but are positively charges. Have the same mass as electrons but are negatively charged. Comprises about 27% of the matter in the universe. An anti-gravity energy comprising 68% of the universe. There has been a long historical debate about the nature of light. Some believed it to be particle like. Other believed it to be wave like. Young"s double-slit experiment in 1801 proved that light was a wave. Max planck in 1900 hypothesized that radiant energy was emitted in discrete bundles, each of which he called a quantum. Quantum physics states that in the micropores of the atom ,the amount of energy in any system is quantized. The idea that the natural world is granular rather than continuous.
