2 How do we describe the wavelike properties of particles mathematically ? The wavelike properties of particles of matter can be described by mathematical functions called wave functions (symbolized by the Greek letter psi: ψ). For a simple particle moving in a straight line (1 dimension) at position x with momentum p with wavelength λ = h / p , a simple example of a possible wave function ψ might be:  x  = amplitude of wave = A sin 2 x
