| So part of the electromagnetic spectrum could be opened up to anyone who uses smart devices. |
| Unfortunately, Earth's atmosphere blocks almost all wavelengths in the electromagnetic spectrum. |
| Light occupies a very small section of the electromagnetic spectrum, and visible light occupies an even narrower range. |
| It isn't hot enough to radiate UV rays but it does radiate in the visible and infrared parts of the electromagnetic spectrum. |
| Most known radiation dangers occur at the high end of the electromagnetic spectrum, and include X-rays and gamma rays. |
| The portrait of a galaxy could thus include information about its appearance in these other bands of the electromagnetic spectrum. |
