Refraction Tank - 200 mm L1-Music & Movement-L2-Musical Instruments-L3-Bells Level 2 introduces more complexThis 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
