Lesson Plan: Matter Waves Physics • Third Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the de Broglie wavelength of massive particles that have a given momentum or velocity.
Objectives
Students will be able to
- recognize that all particles have an associated wavelength called the de Broglie wavelength,
- recognize that the de Broglie wavelength of a particle is inversely proportional to its momentum,
- use the formula .
Prerequisites
Students should already be familiar with
- how to use the formula to find the momentum, , of a particle with mass and velocity ,
- how to use the formula to find the kinetic energy, , of a particle with mass and speed ,
- terms for the basic properties of waves: frequency, period, wavelength, wave speed, and amplitude,
- how to use the formula to find the wave speed, , the frequency, , or the wavelength, , given the other two,
- the names and basic properties of the following particles: the proton, the neutron, the electron, and the muon.
Exclusions
Students will not cover
- electron diffraction,
- the Heisenberg uncertainty principle,
- wave functions,
- quantum tunneling.
