AT&T 24% arth-Sun Geometry 20. What is the anmual rangs of beam spreading at he Most direct y unit beam Date arface unis on. Least direct rays I unit beam Date surface units 21. What is the percentage difference in beam spreading between the highest and lowest amounts at the equator? ne sity 22. Use the right arrow in the bottom right diagram to change the latitude from 23.5 N to a latitude further north (perhaps your latitude). What is the range of beam spreading at this new location Most direct rays 1 unit beam Date surface units Least direct rays unit beam Date surface unitsExplanation / Answer
Answer for 20:
Most direct rays:
1 unit beam = 1 surface units
Date: March 21 (Spring Equinox), September 21 (Fall Equinox)
Least direct rays:
1 unit beam = 1. 090 surface units
Date: June 21 (Summer solstice), December 21 (Winter solstice)
Answer for 21:
Difference in beam spreading between the highest and lowest is
1.090-1=0.090
So the percentage difference is (0.090/1)*100=9%
Alternative way to express: (0.090/1.090)*100= 8.25%
Answer for 22:
The latitude of the new location is not provided. The said diagram is not given. So can not be calculated.
Hope i could able to help you.
