Quanta to Quark / Cathode Ray Question (1 Viewer)

[serge]

Everyone attributes Davisson and Germer
proving De Broglie's hypothesis that objects
can have wave and matter-like properties

but dont the Cooke Cathode Ray experiments
prove the same thing?

Or dont they count because no-one hypothesised it properly

 

[serge]

someone please explain

where's helper when you need him?

 

[jake2.0]

what was Crooke's experiment??

what was Crooke's experiment??

well crooke's tubes had a maltese cross, a spinning wheel
and just a plain tube where you could see that cathode
rays were negatively charged (as deflected by a magnetic field)

 

[jake2.0]

oh right

i think Crooke's experiments were trying to prove one or the other while Davisson and Germer 's showed that a particle can have both types of properties, but not at the same time.

screw it, if they change the syllabus before friday
then i'll think about it

Crookes' experiments did not demonstrate wave like properties of matter, they proved that cathode rays were electrons.

D/G's experiments showed electrons exhibiting the wave-like property of scattering from a nickel crystal, with a measured wavelength that confirmed DeBroglie's hypothesis, h/mv.

not worried bout it anymore...
