Conclusion

This course has introduced two-wave interferences, in order to understand these it also examined the notions of optical path difference and coherence. The reader should remember the following key points: temporal coherence is due to the spectral width, while spatial coherence is related to the source's extension; a monochromatic and point source is coherent both temporally and spatially.

The case studies will focus on Young's slits interferometer used with monochromatic light, and with white light.

The exercises will test your understanding of the main ideas presented in the course.
