Color not perceived | Result if a material absorbs a certain frequency of light, and the frequency is not reflected |
Color Filter | Allow only certain colors of light to pass/transmit through them; they absorb or reflect all other colors. |
absorption and reflection | Results in human perception of color |
Color perceived | Result if the material does not absorb a certain frequency of light, and the frequency is reflected |

Gamma Rays | High-frequency, low-wavelength energy waves. |
Color we see | If the color of light that is shined on the object and the color of light that is reflected by the object |
Cell phones & Radio Waves | Signals that humans cannot sense directly |
Examples of mediums | air or fiber optics |
