Once you have read the textbook chapter and the Reading, answer discussion questions 1, 3- 5 (ignore questions 2 and 6).

Wave models of light help us understand the similarities between light and the movement of water to explain properties of light we can 't see. Refer to diagram 2.1 for example. For example of this we can look at a prism. When a white light shines through it, it splits into seven different colors. ROYGBIV: Red, Orange, Yellow, Green, Blue, Indigo, and violet. This is called the visible spectrum.
