What physics did you just use?

You just sprinted through optics. Reflection and refraction are angle rules, lenses follow 1/f = 1/do + 1/di, and rainbows are dispersion in action. Cameras, glasses, and microscopes are all these rules in hardware.

Key concepts

  • Reflection and refraction
  • Thin lens equation
  • Dispersion
