Split the Stars

This simulation series is based on concept of Limit of resolution. The limit of resolution is the smallest gap that still looks like two points. A round hole blurs every point of light into a small disc. A wider hole or a shorter wave shrinks the discs and splits the pair.

What you'll learn

  1. A round hole's disc Light passes through a round hole. Find the radius of the first dark ring on the screen.
  2. Split two stars Two stars look like one star. Find the smallest mirror that shows them as two.
  3. Headlights Two headlights move away from you. Find the farthest distance at which they still look like two.
  4. Change the colour A telescope just splits two stars. Find the colour that splits an even smaller gap.
  5. Oil microscope A microscope looks at two dots through oil. Find the smallest gap it still splits.
