An object of height 30 cm is placed in front of a spherical mirror with a focal length of absolute value $∣ f ∣ = 15 cm$ . The image formed by the mirror is upright and has a height of 60 cm. Which of the following statements is true?

Correct Answer:

B

Since the image is upright, it must be virtual. The magnification $m$ is given by $m = \frac{h _{i}}{h _{o}} = \frac{60}{30} = 2$ . Since the magnification is positive and greater than 1, the mirror must be concave. Concave mirrors can produce virtual, upright, and magnified images when the object is placed within the focal length. Therefore, the image is virtual and located behind the mirror, and the mirror is concave.
