Packet 7: Bonus 20
In 1999, Zeilinger et al demonstrated this property can be observed in carbon-60 buckyballs. For 10 points each:
[10m] Name this property. Electrons’ behavior in the Davisson-Germer experiment proved they exhibit this property, validating the de Broglie hypothesis that all matter displays it.
ANSWER: wave-particle duality [accept any answer describing something being both a wave and a particle; prompt on wavelike or wave nature or behaving like a wave by asking, "which also behaves like what else?”; prompt on duality or complementarity; prompt on interference by asking “what property of matter causes the interference?”]
[10h] Zeilinger shared the Nobel Prize in Physics for establishing violations of inequalities named for this physicist, which per his namesake theorem rules out all local hidden variable theories.
ANSWER: John Stewart Bell [or Bell inequalities or Bell’s theorem]
[10e] Zeilinger’s co-winner, yachting enthusiast John Clauser, tested the Bell inequalities with an apparatus that only fired two of these particles a week, then took a months-long boating trip while waiting for his results. These particles are the quanta of light.
ANSWER: photons
