Light is an incident on a vertical interface between two mediums as shown in the picture. The medium on the left has an index of refraction n(left) & the medium on the right has an index of refraction n(right). The light comes from the bottom left. Which angle is the angle of incidence? Which is the angle of refraction? Is the speed of light faster on the left or the right side? Or is there not enough information?

Consider a spectrometer based on a diffraction grating. Construct a problem in which you calculate the distance between two wavelengths of electromagnetic radiation in your spectrometer.

Discuss the practicality of the device in terms of being able to discern between wavelengths of interest.
