(6 cards)
1
Q
Define diffraction
A
Waves spreading out after they pass through a gap
2
Q
Which diffract more - longer or shorter waves?
A
Longer waves
3
Q
What is electron diffraction evidence of?
A
Electrons behaving like waves.
4
Q
What other particle also exhibits this behaviour?
A
Neutrons
5
Q
What is the wavelength of a particle given by?
A
Its de Broglie wavelength
6
Q
Equation for de Broglie wavelength:
A
λ = h/p
Where h= plancks constant and p= momentum
