This refraction tank is an ideal resource to show refraction and reflection of light in a liquid. This tank can be filled with water or any other type of liquid. Light rays change direction when it passes one medium into another medium. In other words, the ray bents. The bending is caused by the differences in density between the two substances. By adding different types of liquids to the refraction tank and shining a light bundle on the flat side of the tank, you will see that the light refracts once it travels through the medium in the tank. This is caused by the fact that the density of light (where the light bundle travels through before it hits the refraction tank) is different than the density of the medium. The refraction tank displays the angle of refraction – this is the angle that the refracted ray makes with the normal line (the line that is perpendicular to the line where the two mediums meet at a right angle) – in steps of 1. By changing the medium in the refraction tank, you will see that the light bundle will have a different angle of refraction for each medium. Students can compare the different mediums, and advanced students can determine what medium is in the refraction tank by measuring the index of refraction for that medium. The refraction tank measures 200 mm in diameter.
