3.4 Flashcards
1
Q
who first proposed the wave properties of matter
A
Louis de Broglie
2
Q
equation for the wavelength of mass
A
lamda = h/mv wavelength = planck constant/mass x velocity
3
Q
are electrons waves or particles
A
electrons have wave particle duality
4
Q
what is the heisenberg uncertainty principle
A
since electrons have wave like properties it is impossible to know their precise position and momentum simultaneously
5
Q
heisenbergy uncertainty principle equation
A
deltapdeltaq > h/4pi
delta p = uncertainty in momentum
delta q is uncertainty in position
h is planck constant
6
Q
why is this uncertainty singnificant for an electron and not for a bullet
A
electrons are much smaller
