Quantum Mechanics 1 Guaranteed A+ Review of Properties of a Free Particle (3) 1. Energy is not quantized! 2. They cannot have definite energy! 3. It is always described by a wave packet! 4. wave packet always spreads with time! (just like in classical physics) wave packet a group of superposed waves that together form a traveling localized disturbance, especially one described by Schrödinger's equation and regarded as representing a particle annihilation operator 'lowing o...

Quantum Mechanics-Chemistry Of these electromagnetic waves, which has the longest wave length, greatest energy, greatest frequency, lowest amplitude? ️1. Wavelength is the distance between identical points on successive waves. Wave B has the longest wavelength. 2. Frequency is the number of wavelengths that pass per unit time. Since all electromagnetic waves move at the same speed (the speed of light), equal distances represent equal amounts of time. In the same distance, wave A s...

Quantum Physics Complete Guide Photon Particle of light Intensity + Formula Power per unit area I = P/A Units: W/m² The Photoelectric Effect The emmision of electrons from a metal when electromagnetic radiation of high enough frequency falls on the surface. Threshold Frequency (f₀) Minimum frequency of light needed to eject electrons fromt he surface of the metal Classical Theory Light acts as a wave and the energy of a wave depends on its amplitude (intensity) not its fre...

Quantum Mechanics History Planck ️Energy is discontinuous, quantum Einstein ️Light is both a wave and particle(Photoelectric effect) Bohr ️Bohr Model of Atom, electrons move in fixed orbits around nucleus, energy levels are quantized DeBroglie ️Matter is both a particle and a wave Heisenberg ️Uncertainty Principle:Can't know both location and velocity of a particle. Schrodinger ️Wave functions, orbitals, and quantum mechanical model
