What happens to the wavelengths of light that are not reflected?

When light hits an object, several things can happen to the wavelengths that are not reflected:

1. Absorption: Some wavelengths might be absorbed by the object. This means that the energy of the light wave is transferred to the object. This is often what gives objects their color. For example, a red apple absorbs all colors of light except for red, which it reflects.

2. Transmission: Some wavelengths might pass through the object, a process known as transmission. This is common in transparent materials, like glass or water. The light doesn't change in color because the material doesn't absorb any particular wavelength more than another.

3. Refraction: As light passes from one medium to another (like from air to water), it changes speed, causing it to bend or refract. This can also change the direction of the light waves.

4. Diffraction: When light waves encounter an obstacle or a slit that is comparable in size to its wavelength, it will bend around the obstacle or pass through the slit and spread out. This is known as diffraction.

5. Scattering: Light can also be scattered in many directions. This happens when light hits an object and bounces off in a variety of directions. This is why we can see things from different angles.

So, in summary, the wavelengths of light that are not reflected can be absorbed, transmitted, refracted, diffracted, or scattered.
