9. A particle trapped inside a one-dimensional box
(AB) is likely to be found at one position than another in classical systems.
(AC) cannot moves at any speed within the box in classical systems.
(AD) only occupy certain energy levels if the box size is on the scale of a few nanometers.
(AE) can have zero energy if the box size is on the scale of a few nanom meters.
(BC) may never be detected at certain positions if the box size is on the scale of a few nanometers.
(BD) resuits in four wavelengths equaling the size of the box for n=4. if the box size is on the scale of a few nanomcters.
