Formalizing Wave Mechanics: Light and Sound Properties

Section role: supports the formalization of wave mechanics in section 3, bridging the group investigations from section 2 to the mastery check in section 4 while the teacher lectures. Slides: (1) Title — 'Formalizing Wave Mechanics: Light and Sound'; (2) Speed Comparison — bullets: light at ~3 x 10^8 m/s versus sound in air (~343 m/s) and steel (~5000 m/s); (3) Visible Light Spectrum — image of spectrum, Wavelength range from Violet (~400 nm) to Red (~700 nm); (4) Light Energy and Frequency — bullets: direct relationship, Planck's relation preview; (5) Properties of Sound — bullets: Pitch determination via Frequency (20 Hz to 20,000 Hz), Loudness via Amplitude; (6) Timbre and Wave Complexity — bullets: quality of sound, harmonic overtones; (7) Wave Interactions — definitions and examples of Interference, Polarization, and Dispersion referencing rainbows and noise cancellation; (8) Closing slide: 'How does altering the frequency of a wave simultaneously impact its wavelength and energy?' — hands control back to the teacher for the upcoming mastery check.
