Question

Quizplus · Accepted Answer

Using the mirror equation:

1/f = 1/do + 1/di

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

We have:

1/10 = 1/do + 1/28

Solving for do, we get:

do = 15.6 cm

Therefore, the object is 15.6 cm away from the concave mirror.

The correct answer is D.
