  1. Put do spoznaje da je svjetlost elektromagnetski val Christiaan Huygens (1629. – 1695.) Isaac Newton (1643.- 1727.) Augustin Jean Fresnel (1768.- 1827.)

  2. Armand Hippolyte Fizeau (1819.- 1896.)  d polupropusna ploča zrcalo zupčanik zastor m – broj zubaca c = 4dmf  = t = 2ft

  3. James Clerk Maxwell (1831.- 1879.) Brzina elektromagnetskog vala u vakuumu: c = 310 8 m s-1 Heinrich Rudolf Hertz (1857.-1894.)

  4. Zadatak: Kod prvih mjerenja Fizeau je za brzinu svjetlosti dobio 3,15108 m s-1. Zupčanik je imao 720 zubaca i vrtio se s 12,6 okretaja u sekundi. Na kojoj se udaljenosti od zupčanika nalazilo zrcalo? Rješenje: c = 3,1510 8 m s-1 m = 720 f = 12,6 Hz d = ? c = 4dmf d = 8680 m
