Various colors of laser pointer pens are available on the market, but which one should you choose? It all depends on where you will use the laser pen, actually. For a simple classroom presentation, the red laser pointer will do since this light can travel the small distance of this room. However, if you’re going outdoors, you better use the blue and violet one. How does the color of the laser pointer affect the functionality of the pointer itself? Do you still remember your ROYGBIV and physics class? Red has the lowest frequency while violet has the highest. This means that the color with the highest frequency can travel farther in space. This is the reason why you should choose the violet laser pointer. Always remember that the higher the frequency, the shorter the wavelength. If you’re going to choose the violet laser pointer, you will be flexible in doing any presentations either indoors or outdoors. If it does well outdoors where the distances are much farther, how much more indoors where everything is just a hand of reach? Not only is a laser pointer used for pointing, it is also used in mirror experiments. With lasers, scientists can examine the propagation of light when faced with several mirrors. Also, you can use your laser pointer not only in educational and corporate purposes but also for entertainment. With these, you can even put up your own club inside your room. You can use all the colors of lasers you want, but remember to use cool colors like blue and violet so you’ll not only heat up with the party but also chill with your friends. Aside from creating your very own club in your room with your laser collection, lasers are also used for exhibition.
