A researcher is trying to shoot a tranquilizer dart at a 2.2-m-tall rhino that is 140 m away. Its angular size as seen through the rifle telescope is 9.5 degrees.
What is the magnification of the telescope?

The magnification of the telescope is:
size of image/size of object
= 9.5° / arctan(2.2/140)
= 9.5° / 0.90°
= 10.6 X
size of image/size of object
= 9.5° / arctan(2.2/140)
= 9.5° / 0.90°
= 10.6 X
