This is a detailed lesson plan and powerpoint that covers the topic of wave interference and superposition and extends the knowledge of the previous lesson on the twin slit experiment
Path difference. Coherence.
Interference and diffraction using a laser as a source of monochromatic light.
Young’s double slit experiment: the use of two coherent sources or the use of a single source with double slits to produce and interference pattern.
Production of an interference pattern using white light.
Students are expected to show awareness of safety issues associated with using lasers.
Students will be expected to describe and explain interference produced with sound and electromagnetic waves.
Appreciation of how knowledge and understanding of nature of electromagnetic radiation has changed over time.
