What is a characteristic of collimated light?

A characteristic of collimated light is that it is a narrow beam in a specific direction. Collimated light beams are parallel rays that travel in a consistent direction with minimal divergence. This property makes collimated light effective for various applications, such as lasers, where precision and concentration of light energy are crucial.

Unlike light that spreads out in all directions or that varies in intensity, collimated light maintains its intensity and direction over distance. Additionally, while light can exhibit multiple colors (as seen in white light or when dispersed), collimated light typically maintains a uniform wavelength within its beam. This characteristic is pivotal in therapeutic and medical applications, where precise targeting of tissue without surrounding damage is required.
