What you'll learn

  1. Glow in one colour: Thin films: count the flips, then match the path
  2. Which colour glows?: Which colour a film reflects
  3. Coat the glass: Most light through means no reflection
  4. Coat the lens: Two flips: the quarter-wave coating
  5. Dark flashes: A thinning film flashes
  6. Newton's rings: Newton's rings: a gap that grows as r²
  7. Liquid in the gap: A liquid in the gap shrinks the rings
