    • What does a prism do?

      Q: What does a prism do?

      A: Refracting prisms take advantage of the fact that light makes changes in direction when passing from one material to another, but that different wavelengths bend different amounts. Thus, prisms can split white light, which is actually light made up of multiple wavelengths, coming in at one angle into its constituent colors going out at different angles. They can also do the opposite, condensing multiple color rays into one white ray.
