Matter Wave and de Broglie's Atomic Model

Matter Wave and de Broglie’s Atomic Model

Light has both particle and waves properties at the same time. Likewise, de Broglie (France, 1892 – 1987) thought that such things as electrons that had so far been considered particles might possess wave nature (1932). … more

Line Spectrum and Continuous Spectrum

Line Spectrum and Continuous Spectrum

A solid metal can be made by grouping several hot gaseous (monatomic) metals together. What is the difference between emission spectra in the gas (monatomic) and solid state? The simulation above is a simple example and … more
