The answer depends on the units used for .45 and since these are not given, there cannot be a sensible answer.

The range is the difference between the highest and the lowest number amongst a group of numbers. Consider the numbers:23, 45, 23, 3, 10, 106, 200, 45, 54.The range is the largest (200) minus the smallest (3) which is 200-3 which is 197.
Because the bottem mirror which is set and 45 degrees the light bounces off of and goes up at exactly 90 degrees that light then bounces off the top mirror and out a hole for you to look through.
The law of reflection: When a ray of light reflects off a mirror, the angle of the incidence ray is equal to the angle of the reflection ray. Therefore, an incidence ray of 45 degrees will have a reflection ray of 45 degrees. As both rays are equal, either side of the normal line, then adding both angles equals 45 + 45 = 90 degrees. The normal line is a line perpendicular to the surface of the mirror.

Top of the ground 45 meters higher than its high-rise buildings must be set above the navigation light. For general purpose lighting differ, beacon lights are not lit but the long shiny, flash frequency is not less than 20 times per minute, not more than 70 times per minute...

Kinetic Energy
Because of the serpentine motion - the long and winding road - that light and energy take as they go through the universe.
One situation is the movement of light through water. If you are ever in a pool, you may notice the different light patterns, or in the ocean, waves of light split up into their capability of reaching the bottom. Also, light diffracts during rainfall (rainbows).
The energy related to movement is called kinetic energy.
