After completing this tutorial, you will be able to complete the following:

- Explain the wave nature of subatomic particles using de Broglie’s equation.

What did Louis de Broglie prove in 1924?

~ Louis de Broglie proved that photon rays could behave as particles and as waves. LHe used the equation to indicate that all matter possessing velocity and mass will also have a wavelength. He proved this dual nature was also valid for matter, and won the Nobel Prize in Physics in 1929.

What is unique about Planck's constant in de Broglie's equation?

~ Planck's constant is so small that in order to observe the wavelength, the product of the matter's mass and velocity must also be very small. This can only be observed in subatomic particles with small masses, such as an electron.
