Refraction and Reflection (9-12)

This W.E.T. is centered around principles of refraction and reflection of electromagnetic waves. Water treatment plants often use the turbidity of water to determine what kinds of contaminants are in the water and they also use specific spectrums of light to disinfect water as well.
Using trigonometric identities and Snells Law students identify the index of refraction of various solutions. Once students calculate the index of refraction of water and vinegar respectively they can find a range of values in which an unknown index of refraction resides.
