The surface of the water appears here in beautiful shades of blue, yellow, green, and pink. A drop breaks the surface and starts concentric circular ripples that travel on the surface of the water outward from that point. What do we know about the nature of water and how it absorbs, transmits, and reflects light? How does the reflection of light at particular wavelengths affect the colors our brains interpret? How do waves travel? What affects their speed and frequency? What do water waves have in common with light? How can your knowledge of these basic physics principles be applied to technology, such as the fiber optics used in telecommunications and in arthroscopic knee surgery? The answers to these questions and many more can all be learned through your study of Physics.
