Lesson: Matter Waves High School PhysicsPhysics
In this lesson, we will learn how to calculate the de Broglie wavelength of massive particles that have a given momentum or velocity.
Sample Question Videos
If an electron and a muon have the same speed, which particle has the greater de Broglie wavelength?
Which of the following formulas shows the relation between the de Broglie wavelength of a particle, , its momentum , and the Planck constant ?
A muon has a rest mass of kg. If the muon is moving at a speed of 20 m/s, what is its de Broglie wavelength? Use a value of J⋅s for the Planck constant. Give your answer to 3 significant figures.
