**Matter can behave as a wave and therefore will have a corresponding wavelength**. The **De Broglie Wavelength** equation relates wavelength to velocity or speed.

The constant **h **stands for the** Planck constant with a unit of m ^{2} kg / s.**

The mass of an electron is **m= 9.109×10 ^{−}^{31 }kg**.

Calculate the velocities of electrons with de Broglie wavelengths of 1.0 x 10 ^{2} nm and 1.0 nm.
