$An Introduction to Refractometry$

An Introduction to Refractometry

You’ve lost the key to your locker in the swimming pool. You spot it lying on the bottom of the shallow part of the pool, reach in to take it – and your hand misses. The refraction of light at the boundary of two different materials can be explained as easily as that.
