A concave mirror creates a real, inverted image of a dog 2 m away from its surface. If the image of the dog is 10 times larger how far away is the dog sitting from the mirror? Please show your work using grasp.

Answer:

Using the formula for the image distance of a concave mirror:

1/di + 1/do = 1/f

Where di is the image distance, do is the object distance, and f is the focal length.

We can solve for do:

do = (f*di)/(di-f)

Given:
di = 2 m
f = 2 m

do = (2*2)/(2-2)
do = 0 m

The dog is 0 m away from the mirror.
