Question

Which relation gives the de Broglie wavelength of a particle with momentum \[p\]?

Options

• \[\lambda=\frac{E}{c}\]

• \[\lambda=\frac{p}{h}\]

• \[\lambda=\frac{h}{p}\]

• \[\lambda=hp\]

Answer 1

The de Broglie relation is \[\lambda=\frac{h}{p}\]. It gives the wavelength associated with a particle from its momentum and Planck's constant.
