Refraction of light experiment. Apparatus used to show how light is refracted when passing from one medium to another with a different refractive index. Here, a glass test tube containing air has been lowered into a beaker of glycerine. As the refractive index of glycerine and air is different, but that of the glass and glycerine are about the same, the test tube is visible inside the beaker, due to the air inside it.
