Pointer Distance
January 25th, 2010
how can you increase the distance a laser pointer goes?
please correct me if I’m wrong, but i thought that if the frequency of visible light is higher, then the visible light will travel farther. how would you increase the frequency and by doing so increase the distance? doing this with a red laser pointer, by the way.
The frequency has nothing to do with how far the light travels, it just influences how the light interacts with matter and other light. Also, the light travels a lot farther than you can see, it just spreads out from the original beams so that it isn’t focused enough to notice anymore. If you want it to stay focused for longer all you have to do is increase the intensity by putting more energy into the laser. In other words, get a bigger battery.
