1.
In a double-slit experiment with single electrons, an interference pattern builds up. This shows that
electrons show wave behaviour
electrons are not charged
electrons attract each other
electrons are photons
2.
If a detector determines which slit each electron passes through, the pattern
becomes brighter
becomes two single-slit patterns without interference
is unchanged
is shifted
3.
The probability of finding a particle at a point is proportional to
the wavefunction
the momentum
the square of the wavefunction amplitude
the wavelength
4.
According to the uncertainty principle, if the uncertainty in position decreases, the uncertainty in momentum
decreases
is unchanged
increases
becomes zero
5.
Quantum tunnelling explains
alpha decay
beta decay of the neutron
the photoelectric effect
refraction
6.
Which of these shows particle-like behaviour of electrons?
An interference pattern
Diffraction by a crystal
A decreasing wavelength with voltage
A single spot on a detector
