For a given observation, it adopts the property of one or the other. In reality, all particles exhibit wave properties *sometimes* and all waves exhibit particle properties *sometimes*. Each particle has a wave function that determines how likely it is to be somewhere at any point in time. -By equating the equations for momentum of photons and particles, the wavelength of a particle can be determined.

Where $\lambda$ is the wavelength of the particle, $m$ is its mass, $v$ is its velocity, and $h$ is Planck's constant: $$\lambda=\frac{h}{mv}$$ Therefore, wavelengths of "particles" are only really significant for small masses at high speeds rather than large masses at lower speeds.
