Question
A concave mirror produces a three-times magnified (enlarged) real image of an object placed 10 cm in front of it. Since the image is real, the magnification is
m = +3
m = -3
m = +1/3
m = -1/3
Answer
m = -3
Detailed Explanation
Since the image is real, magnification carries a negative sign; being three times magnified gives m = -3.
