Laser light is monochromatic, directional, and coherent Monochromatic: The light emitted from a laser is monochromatic, that is, it is of one wavelength (color).In contrast, ordinary white light is a combination of many different wavelengths (colors).Directional: Lasers emit light that is highly directional.hat is the only characteristic of laser light. Ordinary light has a bunch of light waves where the timing of the waves has no relationship from wave to wave, so it is not coherent. Let me touch on why what other people have said is not right.
White light (for example, what comes out of a flashlight) is actually made up of many waves that each exhibit one of the different colors of light (red, orange, yellow, green, blue, and violet). The reason that different waves of light appear to be different colors of light is because the color of a light wave depends on its wavelength. For example, the wavelength of blue light is about 450 nanometers, while the wavelength of red light is about 700 nanometers. A light source that gives off white light is therefore emitting multiple waves of light with a wide range of wavelengths from 450 nanometers through 700 nanometers.
