The diameter of Mars is 6794 km , and its minimum distance from the earth is 5.58×107 km. When Mars is at this distance, find the diameter of the image of Mars formed by a spherical, concave telescope mirror with a focal length of 1.65 m.

Please make sure the answer is in the right units! Thank you.

Answer #1

Lateral magnification: y ′ = y(−s ′/s)

| y ′| = y(s ′/s)

| y ′| = 6794 x 103 (1.65 / 5.58 x 1010)

|y'| = 6794\times 10^{3} \times \frac{1.65}{5.58 \times 10^{10}}

|y'| = 0.2008 mm
