| You wouldn't see the rainbow effect if you used two reflecting surfaces an inch apart because that distance too large to diffract visible light. |
| Likewise, an optical microscope cannot resolve features much less than a wavelength of visible light across. |
| Under visible light irradiation, much longer durations were necessary to achieve similar absorbance decreases. |
| There could also be waves of electromagnetic energy both shorter and longer than visible light. |
| There should be a visible light and audible warning when the treatment electrode is energized. |
| Ultraviolet and visible light comprise only a small portion of the wide ranging electromagnetic radiation spectrum. |
