Objectives:

After completing this module, students will be able to predict the maxima and minima in diffraction patterns produced by a single slit, two slits, and a diffraction grating.  They will also be able to work problems involving interference from thin films.  Students will be able to calculate the maximum resolution of optical instruments.

Diffraction and interference

Study the on-line material:

• Single slit diffraction

• Double slit interference

Thin film interference

Study the on-line material:

• Thin-film interference

• Resolving power

• Interferometers
