Heisenberg Uncertainty Principle
b) A particle does have a definite location at a specific time, but it does not have a frequency or wavelength.
c) Inbetween case: a group of sine waves can add together (via Fourier analysis) to give a semi-definite location: a result of Fourier analysis is this: the more the group shows up as a spike, the more waves it takes to make the group.
