Their formula stated: I = Intensity However, this formula also had a problem. For large wavelengths it fitted the experimental

WAVE EQUATIONS, WAVE FUNCTIONS AND ORBITALS
science-blogs.ucoz.comWAVE EQUATIONS, WAVE FUNCTIONS AND ORBITALS According to the quantum mechanical concept, electrons in atoms and molecules are considered as ‘standing waves’ or ‘stationery waves’ (similar to vibrations in a stretched string, but in 3 dimensions). Properties of a wave Consider a standing wave in a stretched string.

depthome.brooklyn.cuny.eduStanding waves are discrete phenomena, meaning that they only occur at specific values of wavelength. The distance from a node to an adjacent node (or from an antinode to adjacent antinode) is half of the wavelength. In order to form a standing wave a resonance condition has to be satisfied: 2 n L (3)
