A.
Same frequency
B.
Same amplitude
C.
Same phase
D.

Solution
Answer: Option D
Solution:
In a Laser all the atoms emit the light waves of same frequency, amplitude and phase. A laser is a device that emits light (electromagnetic radiation) through a process of optical amplification based on the stimulated emission of photons. The term “laser” originated as an acronym for Light Amplification by Stimulated Emission of Radiation.
