This approach will allow us to talk about the phenomena of interference as well as diffraction.
The understanding of the notion of diffraction will be used to determine the Rayleigh criteria and finally the resolving power of an optical system.
In the second part of the lecture, we will study gratings using the wave approach. An example of an amateur spectroscope for astronomy using a reflective grating will be shown.
Don't forget to stop music in the gadget at the right side panel.
