Logarithmic scale is one in which the logarithms are plotted as against the linear scale where the values are plotted. That means in log scale, the distance 1-10 will be the same as 10-100, and, will be the same as 100-1000, and, so on. My preference is to use linear scale, though.

Materials That Glow Under Black Light. There are a lot of everyday materials that fluoresce or glow when placed under a black light. A black light gives off highly energetic ultraviolet light. You can't see this part of the spectrum, which is how 'black lights' got their name. Fluorescent substances absorb the ultraviolet light and then re-emit it almost instantaneously.
