Spherical Mirrors: Image Formation with Concave Mirrors - Calculation Example

[slyman]

A concave mirror reflects an image of the Moon 6 cm form the mirror. If a coin is placed 8 cm from the same mirror, where will its image be?

I just want to make sure of something. Since the Moon is very far from the mirror, f is simply the image distance of the Moon. Therefore, all I have to do is plug in f=6 and the object distance=8 in the mirror equation to find the image distance.

Yeah. Thats right.
