| Your body needs this to make Vitamin D | ultraviolet |
| The particle that carries radiant energy. | photon |
| Electromagnetic radiation with the shortest wavelengths | gamma |
| The most energetic EMW's. They have the most photon energy | gamma |
| The waves that are considered 'radioactive" | gamma |
| This is vital to Earth because it blocks most of the harmful UV radiation. | ozone layer |
| The MAIN use for these is communication | microwaves |
| Police use radio waves in this method to detect speeders. | RADAR |
| These waves are used to kill bacteria on medical supplies and have frequencies slightly higher than visible light. | ultraviolet |
| These have the lowest energy of the spectrum. | radio |
| As the wavelength of an EMW gets longer, the frequency..... | decreases |
| As the wavelength of an EMW gets shorter, the frequency...... | increases |
| The entire range of EMW frequencies | EM spectrum |
| We use these frequencies for many things including remote controls | infrared |
| These wavelengths are slightly longer than visible light | infrared |
| This color has the most energy due to a higher frequency | violet |
| This color has the lowest energy due to a lower frequency | red |
| THese are involved with MRI's | radio waves |
| These are absorbed by bone and other dense body tissue | X-rays |
| These come from the breakdown of atomic nuclei | gamma |
