but very good frequency resolution
- but very good frequency resolution
- hum G near 200 Hz. Then F# near 188 Hz.
- difference easy to hear
- good ear can detect 3 Hz difference from 20 Hz to 20,000 Hz
- Eye is just the opposite
- very good imaging resolution
- very poor frequency resolution
- only Red, Green, and Blue (and various mixtures)
Wave architecture
- Two types
- Longitudinal (sound waves)
- motion along direction of wave propogation
- demo with vertical slinky
- Transverse (light waves)
- motion perpendicular to direction of wave propogation
