To calculate: The area of each section of a mirror.
Answer to Problem 37E
The area of each section of the mirror is 2.1
Explanation of Solution
Given information: the W.M. Keck Observatory has two telescopes. Each telescope has a mirror composed of 36 identical sections, fitted together. The total area of the mirror is 75.8 square meter.
Calculation:
Total Area = 75.8
Number of sections = 36
To calculate the area of 1 section of mirror, divide the total area by number of sections,
= 2.1
Hence, the area of each section of the mirror is 2.1
