1. Background

This experiment gives very clear graphical proof to students about the diffraction and interference nature of light waves. We can get similar results by replacing the light sensor and light source with sound sensors and 2 sound sources.

2. Objective

	To observe the diffraction patterns of light.
	To study the interference effects from two slits (Young's slits).

3. Equipment List

	Datalogger interface connected to a PC
	Light sensor
	Double slits
	Light source
