WEEK 5-6 : Interference of light
Student Learning Objectives
- To recognize the experimental evidence for the wave nature of light.
- To understand how and why interference of light waves occurs.
- To understand how constructive and destructive interference are related to the path-length difference.

- To understand the conditions for constructive and destructive interference in thin films.
- To study the spreading of waves due to diffraction.
- To understand how light diffracts through single slits and circular apertures.
- To understand how diffraction limits the resolution of optical instruments.
