Quantum Mechanics
Why quantum mechanics? Because the failure of Newton’s law at a level of atoms and their constituents, the Q.M. provides a new set of laws and mode for microscopic systems. ○ “Exchange particle” is a lack of C.M. ○
So That: the dual (particle-wave)-nature of every thing in the world provide by Q.M.
The system of range (Aº) to (F) and beyond:
Development of Q.M. ○ Blanck’s
solution of black-body radiation ○ Photoelectric effect ○ Bohr model of atom ○ De, Broglie wavelength of material particles
○
Planck's solution of black-body radiation
Other phenomena like photoelectric effect and model of atom explain according to Q.M. . • the classical wave theory ➔ • The photoelectric effect ➔

When the black-body oscillator causes exchange energy in fixed discrete amounts, Bohr noticed that and proposed the model of hydrogen atom.
