Question
It is possible to get complete coherence in a Lasera.Falseb.Truec.Occasionally
Solution
b. True
Lasers are designed to produce and amplify light. The light produced by a laser is monochromatic, directional, and coherent. These three properties distinguish laser light from ordinary light. Coherence means the light waves are all in phase with each other and have the same wavelength. This property allows the laser light to stay focused over great distances, even in space.
