In this lesson, we will learn how to calculate the de Broglie wavelength of massive particles that have a given momentum or velocity.
Students will be able to
Q1:
An electron has a rest mass of 9.11×10 kg. If the electron has a kinetic energy of 1.14×10 J, what is its de Broglie wavelength? Use a value of 6.63×10 J⋅s for the Planck constant. Give your answer in scientific notation to two decimal places.
Q2:
What is the kinetic energy of a muon that has a de Broglie wavelength of 4.10×10 m? Use a value of 1.89×10 kg for the rest mass of a muon and a value of 6.63×10 J⋅s for the Planck constant. Give your answer in scientific notation to two decimal places.
Q3:
If an electron and a muon have the same speed, which particle has the greater de Broglie wavelength?
