Answer:
Population inversion, in physics, the redistribution of atomic energy levels that takes place in a system so that laser action can occur. Although absorption and emission of energy is a continuous process, the statistical distribution (population) of atoms in the various energy states is constant. ...
laser inversion is photon that can stimulate the production of other photons of exactly the same wavelength because of stimulated emission of radiation.

Answer:
B
Explanation:
If the light is pointing down ,and then hits a surface of a 60 degree angle, then the direction will be away from the light since the light is touching a surface that is flat of a 60 degree angle then it will reflect off of it Perpendicular.
Answer: distance
Explanation:
Speed equals distance over time
Meaning time is on y axis and distance is on x axis
Time will always, Always be on y axis
So in any formula time will be on y axis and your other unit will be on x axis in this case s=d/t d being distance
