Given this picture, what’s the best question I could write to accompany it? I’m favoring “What is the most likely liquid in the dish? (give a list of liquids with indices of refraction)”

My kids completed their refraction lab today and I snapped a few photos in case I want to use them on an upcoming test. I’m beginning to think I need to revisit “lab questions” on my tests.

  1. From Mike on Twitter: “If we switch the light source to come in at 130 instead of 115, how many degs away from 110 will the light ray exit?” (mostly because I don’t want to forget this awesome question)

  2. From Marco on Twitter: “if the light source it made to revolve around the origin in a ccw fashion, the emanating beam will become more horizon/more vert/unchanged.”
