Final answer:
When light waves strike a red object, they are reflected. The color of an object is determined by the wavelengths of light that are reflected.
Step-by-step explanation:
When light waves strike a red object, they are reflected. This means that the light waves bounce off the surface of the red object and are redirected away. The color of an object is determined by the wavelengths of light that are reflected. In the case of a red object, all colors of light except red are absorbed by the object, causing only red light to be reflected.
