Aim: to observe Diffraction Patterns using a Low Power Laser
See Diffraction, Diffraction Patterns, Young's Experiment, The Diffraction Grating
 
Observe and draw (or photograph) the diffraction patterns produced by
- single slits of different widths (note the width of the slit)
- double slits of different slit separation (note the slit widths and separations)
- multiple slits and diffraction gratings (note the number of slits per mm)
Use a diffraction grating to measure the wavelength, λ of the laser light.
For constructive interference:
By measuring D and y, we can find the angle θ and hence λ can be found.
