Mar 28, 2016

Louis de Broglie extended the notion of wave motion from light to other particles, such as electrons. It is possible to calculate a de Broglie wavelength for anything, including an elephant!

#### Explanation:

The formula is

If you do the calculation, you will find out that the de Broglie wavelength for big objects like an elephant or a tennis ball is immeasurably tiny. It is only for very tiny objects like electrons that the concept really has much significance.
