A. Light waves travel at a speed of about 300,000,000 m/s in empty space.
B. Green plant leaves absorb the red light waves found in sunlight.
C. A clear glass window allows people to see what is happening on the other side.
D. A rainbow results when visible light waves pass through water droplets in the air.

Explanation:

In this short-wavelength limit, wave propagation gives way to ray propagation (which is a special, approximate case of the former), and specifically to Fermat's principle for the mathematical description of light. This principle states that light rays starting at
