Note: We will have a quiz on Friday (F) and Monday (A).
Review the variations of the Snell's law equations and create/solve a problem which asks for:
- refracted ray angle
- refracted ray wavelength, speed, and frequency
Consider an equilateral triangular prism of glass (n = 1.5). A light ray hits it on the left side such that the ray refracted inside the glass runs parallel to the bottom of the prism. Find the initial angle of incidence (theta 1) on the left side. Find also the exiting angle on the right side of the prism.
A (also): Finish informal lab calculations. Look up the index of refraction of salt water. Are you close? Does it change a lot from regular water?
