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.
This type of light is useful for lots of technologies and instrumentsâeven some that you might use at home! How does a laser work? Light travels in waves, and the distance between the peaks of a wave is called the wavelength. Each color of light has a different wavelength. For example, blue light has a shorter wavelength than red light. Sunlightâand the typical light from a lightbulbâis made up of light with many different wavelengths.
