Ok let me in on this boys and girls, and i do physics
haha quanta to quarks.
determination of wave-particle duality of light -> chadrick n fermi fired electrons from a cathode ray at nickel crystal to determine if it has wave characteristic
at first, no diffraction was detected. but then, oxygen found a way into the experiment which oxidised the nickel crystal.
Chadrick and fermi tried to counter this by heating the nickel crystal (what i was trying to imply. lol) and but instead, created crystal regions that were larger than the electron beam.
in the end, they detected wave-particle duality in light/emr..
lol . .tht's off the top of my head
tooo be on topic: i don't think felt tip will effect it much. but u better bring a spare pen just in case . .
