WARM UP
“The service we render others is
the rent we pay for our room on
Earth.” -Sir Wilfred Grenfell
1.What does this mean to you?
2.How can you be of service to others?
Introduction to Quantum Mechanics
Wave Mechanics
• Transmit energy
• Wavelength and Frequency
– Inversely proportional
Wave Mechanics
• Electromagnetic spectrum
– Continuous gradient
Quantum Theory
• Max Planck’s emission spectra show
levels of energy in e-
Quantum Theory
• Light released when e- drop from a higher level
(excited state) to a lower one (ground state)
Wave / Particle Duality
• Albert Einstein’s photoelectric effect experiment
showed certain light waves release metal e– Light is both a wave and a particle (photon)
The Big Bang Theory
Wave / Particle Duality
• Louis de Broglie – Dual Electron
• e- behave like both particles and waves
Quantum Mechanics
• Erwin Schrodinger
– Energy levels/shells are really wave regions
Quantum Mechanics
The Big Bang Theory
Quantum Mechanics
• Heisenberg Uncertainty Principle
– Werner Heisenberg
– You can’t simultaneously
know the speed and position
of an e• You can’t “see” the wave
and particle at the same
time
Quantum Mechanics
