| An elementary understanding of the visible spectrum of light as it relates to the wavelength. |
| Eight pigments cover the visible spectrum, and four cover the ultraviolet region. |
| The opal's colour ranges across the visible spectrum, from deep red to violet. |
| These wavelengths correspond to colors in the visible spectrum ranging from violet to blue to green to yellow to orange, and then red. |
| The blue filter is measuring blue light in the visible spectrum, not the ultraviolet light to which platinum materials are sensitive. |
| Even though pulsars emit light in the visible spectrum, they are far too small and far away for us to detect any of this visible light. |
