1. Because the sandwich is only a few angstroms thick it transmits visible light - but it reflects longer wavelength heat radiation. 2. This gas absorbs visible light so well that plants could not photosynthesize even if they somehow retained their leaves. 3. Until recently, such wavelengths have been ignored because neutral hydrogen absorbs it in the same way fog absorbs visible light. 4. Visible light has a longer wavelength than UV radiation. 5. The shod-wave infrared that lies closest to the red end of the visible spectrum behaves like visible light. 6. Photographs using SWIR radiation rather than visible light can be taken with an ordinary camera and special film. 7. An imaging system that creates visible light to produce infrared movies is being used to inspect the network of tunnels that form the Metro in Paris. 8. Astronomers now take the entire electromagnetic spectrum into account, not just visible light. 9. At this temperature, the compressed gas radiates both visible light and high-energy ultraviolet radiation. 10. A maser is the radio counterpart of a laser, which amplifies visible light. |
