Answer to Question #263622 in Physics for Rethabile

Question

Question 9 

An object is placed in front of spherical mirror, and the magnification of the system is m = -6. What does this number tell you about the image?

Question 9 options:

A) 

The image is a real image

B) 

No option is correct

C) 

The image is larger than the object

D) 

The image is inverted relative to the object

E) 

a, b and c

Answer 1

The magnification equation for the spherical mirror can be written as follows:

$$m=-\dfrac{d_i}{d_o}.$$

In order to the magnification of the system be -6 the image distance must be positive. Therefore, the image is a real image. Also, $m=-6$ means that the image is inverted relative to the object and larger than the object. Therefore, the correct option is (E).

Answer:

E) a, b and c
