Lesson 12: Bohr to Heisenberg

Bohr El- travel in FIXED ORBITS which are Energy levels El- can jump from level to level by absorbing and emitting E

Heisenberg Studied el- Did thought expmt and used mathematics El- do not follow rules of “classic physics” Uncertainty Principle You can know the position or the momentum of el- , BUT not both (weird!) To “see” an el-, you would use small wavelengths of light, but this light has hi E, So, when this light hits an el-, you “see” it and at the same time the el- is changed El- should be thought of as being in ORBITALS: Areas of high probabillity
