I had an opportunity to travel in Wisconsin and along the way I took the picture above. As I reflected on our current class discussions of dual properties of light as a wave and light as a particle, considering the visible spectrum, what would be the wavelength of lights that you see as green and orange? How would you measure their frequencies? Why do we see green color like a green grass, green folder, and white colors? Was the color being absorbed or reflected? Why leaves change colors in fall? What do you think?
