Answer: The reflected wave has less energy

Step-by-step explanation:

The incident wave would be the light wave before it comes in contact with the CD. Once the incident wave hits the CD, there is a reflected wave which will have some portion of energy from the incident wave. The reflected wave is a different color from the incident wave due to the reflected wave having less energy. Less energy means a different wavelength of visible light

Answer:

The smooth surface of the CD causes wavelengths of light to scatter. The CD at this point acts somewhat like a prism splitting white light into the colors of the rainbow. This is called the visible spectrum of light and is composed of the colors red, orange, yellow, green, blue, indigo and violet.
