Davisson and Germer's electron experiment demonstrated what?
AQuantisation of charge
BWave nature of matter
CExistence of the nucleus
DParticle nature of light
Answer & Solution
Correct answer: B. Wave nature of matter
Electrons diffracted from the crystal like waves, giving direct evidence that matter has wave character.
