1. Graph the index of refraction by plotting sinθ1 over sinθ2 and determining the slope of the line.
  2. Try repeating the experiment with the dish empty. What is different about the refraction of the light passing through the empty dish from the refraction of light passing through the dish filled with water?
  3. What would happen if the water in the dish were replaced with a denser liquid? What would be different about the refracted angle?
  1. In the juice and wine industry, a device called a refractometer is used to measure the sugar level in juice. How would the refraction of light be used to determine the sugar content of a solution?
