Lesson: Interference of Light Waves Physics

Start Practising

In this lesson, we will learn how to define wave interference and describe the constructive and destructive interference of waves that are mutually in or out of phase.

Lesson Plan

Students will be able to

define the resultant displacement of a point where two wave pulses overlap,
describe the resultants of pairs of wave pulses as they overlap,
define phase difference between pairs of waves from the relative positions of the maximum positive and negative displacements of the waves,
recognize constructive interference as completely in phase pairs of waves,
recognize destructive interference as completely out of phase pairs of waves.
