Wave Reflection, Absorption & Transmittance Activity for Kids
- 1Beaker Made of Borosilicate Glass
- 1Clear Glass Container
- 1Liter of Vegetable Oil
- 1Put the borosilicate glass beaker into the larger glass container.
- 2Fill the beaker and then the container with the oil about 2/3 of the way to the top.
- 3Watch the beaker disappear!
How It Works
The borosilicate glass beaker disappeared! This is possible because the oil and glass have very similar optical properties. Light waves transmit through both materials without much reflection, absorption, or refraction. Normally, we see objects when light reflects off of them and into our eyes. Because of the similar properties of these two materials, light passes from one into the other without reflecting into our eyes, so we cannot see the beaker!
