Summary
De Broglie (1924) has the idea: Particles act like waves!
Waves show interference effects: Standing waves: L = n ? / 2, n=1,2,… (like a piano or guitar)
Demonstrated by Davisson-Germer experiment (1927): electrons act like waves!
Explains the quantized energies of the Bohr atom
Schrodinger (1926): Equation for wave function ?(x,t) for a particle --- Still Today the Basic Eq. of Quantum Mechanics
( ?(x,t) ) 2 is probablity of finding the particle at point x and time t. More about this later.
Explains all of Chemistry!
