Question

An object is located 50.0 cm from a convex mirror. the focal length is 25.0 cm. what is the image distance? Use the equation di=dof/d0-f
A.50.0 cm
B.16.7 cm
C.-50.0 cm
D.-16.7 cm

Answer 1

Since you already give the equation, we simply identify the given.
With do = 50.0cm and f = 25.0cm, so
di = (50*25)/(50-25) = 50 cm
The answer is A.
