Wavelengths [Lasers]

One of the applications (one of the best in my perspective as of now) that lives on concept of vectors are lasers. As we all know, lasers are waves of light or signal that are being beamed from one location to another, which is possible because of the mathematics of vectors. Typical usage of this technology is fiber optics (firing a laser through a medium where it bounces light travelling in its superb speed!), which greatly helped our entire race in communicating effectively despite great distances. 🙂
