Step 1 of 3

Le | 1 Pillars of Classical Physics ● Electrodynamics (Maxwell), Mechanics (Newton), Optics, and Thermodynamics (Gibbs) ● Relativity:​ery high-energy particles ● F = ma​: ​particles at normal energy and mass ● Quantum Mechanics​ : low-energy particles (in chemical systems) Electromagnetic Radiation ● Electromagnetic Radiation:​energy where electric and magnetic fields propagate through space as waves ○ Waves:​disturbance that transmits energy through space ■ Traveling Wave:​wave in which medium moves in the direction of propagation ■ Anatomy of a Wave ● Amplitude ​ (A): maximum height if wave above/below center line ● Wavelength ​ (入): distance between two peaks/troughs (​nm​) −1 ● Frequency​(v​ ​): # of peaks/troughs passing through a given point over time (Hz ) s ● c (velocity of wave) = v × λ ○ If wave is EM radiation, v = c ≈ 3.0 × 10 s ■ Interference:​when two waves meet ● Constructive (addition of two waves) vs. Destructive (cancellation of two waves) Prelude to Quantum Theory
