| Most tinted and mirrored films include a coating to block the transmission of ultraviolet light. |
| All the light that we see is made from electromagnetic waves, and so are infra-red and ultraviolet light, microwaves, radio waves and X-rays. |
| However, the longer wavelength rays of ultraviolet light can also cause problems. |
| It glows under ultraviolet light and can be broken down so that a millimetre of hair would be enough to give an analysis. |
| Although new stars primarily radiate ultraviolet light, the dust they generate absorbs that light and re-emits it in the near-infrared. |
| The electric field set up inside the tube excites atoms of mercury gas, making them emit ultraviolet light. |
