Question

Quizplus · Accepted Answer

Laser light is monochromatic, meaning it contains only one wavelength of light. It is also coherent, meaning the light waves are in phase with one another. Laser light is very intense and does not spread much, allowing it to be focused into a narrow beam. However, laser light is not a combination of wavelengths.
