3.6 - wave particle duality Flashcards
1
Q
define wave-particle dality
A
waves are dual natured, they have both particle and wave like properties. Depending on the circumstance, one property is prioritized over the other
- particles are also duel natured
2
Q
when does the most diffraction occurs
A
when the gap size = wavelength
3
Q
how do EM waves show
- wavel ike properties
- particle like properties
A
Wave; diffraction
Particle; Photoelectric effect
4
Q
how do e- show
- wavel ike properties
- particle like propertoes
A
Wave; diffraction
Particle; deflected by magnetic fields
5
Q
experiment showing e- diffracting
A
- a beam of high impact e- going through a graphite crystal sheet
- e- pass through the gaps between the crystals, dir=fractiong at diff angles
- hit a fluorescent screen and produce concentric cirecles
6
Q
De Broglie wavelength equation
A
λ = h / (mv)
7
Q
how do you produce less spread out circles from e- diffraction
- explain
A
increase the e- speed, reducing its wavelength, thud decreasing diffraction
- so e- spread out less
