$\bullet$  X = h / mv. This equation implies that a moving particle can be considered as a wave and a wave can exhibit the properties of a particle.

$\bullet$  For a particle with high linear momentum (mv) the wavelength will be so small and cannot be observed.

$\bullet$  For a microscopic particle such as an electron, the mass is of the order of 10-31 kg, hence the wavelength is much larger than the size of atom and it becomes significant.

$\bullet$  For the electron, the de Broglie wavelength is significant and measurable while for the iron ball it is too small to measure, hence it becomes insignificant.
