Lesson Plan: Two-Slit Interference Physics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the positions of points of maximum and minimum intensity in interference patterns generated by double slits.

Objectives

Students will be able to

  • use the formula 𝑑𝜃=𝑛𝜆sin to calculate angle, wavelength, slit spacing, and order number in two-slit interference patterns,
  • use the formula 𝑠=𝑛𝜆𝐷𝑑 to calculate distances between fringes in two-slit interference patterns,
  • compare calculated distances between fringes using 𝑠=𝑛𝜆𝐷𝑑 and using trigonometry.

Prerequisites

Students should already be familiar with

  • coherent waves,
  • constructive and destructive interference.

Exclusions

Students will not cover

  • single-slit diffraction patterns,
  • 𝑛-slit interference,
  • relative intensity at arbitrary angles.
