Lesson Plan: Holography Physics • Third Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe how the phase differences between coherent light waves can be used to produce three-dimensional images.
Objectives
Students will be able to
- define the terms illumination beam, reference beam, and object beam,
- describe how a holographic plate records information on the phase differences between waves from different points on the surface of a three-dimensional object,
- describe how the appearance of a holographic virtual image depends on the relative positions of reference, illumination, and object beams.
Prerequisites
Students should already be familiar with
- the phase angle of a wave,
- the phase difference between two waves,
- coherence,
- the path difference between two waves,
- the definition of the term virtual image.
Exclusions
Students will not cover
- any calculations other than path differences and phase differences determined by path differences.
