2. With determining the index of refraction for water, the water is placed in a box made of plastic. How would this change the value that you found from the actual value? 3. A person with normal vision can see fairly well in air. However, when underwater their vision is blurred. Comment on why this is. 4. If the speed of light were the same in all materials, would refraction still occur when light passes from one material to another? 2.
