Physics Help!!!?

This is a four part question.. I only need help on the last part.


Consider a concave mirror with a focal length of 15.84 cm.


a) Find the image distance when the object distance is 15.84 cm. I found this to be 0 and it was correct.


b)Find the image distance when the object distance is 7.92 cm. I found this to be -15.84 and it was correct.


c) Find the magnification of the image for part b. I found this to be 2 and it was correct.


d) Describe the image for part b (THIS IS THE ONE I DON'T KNOW HOW TO DO!!!) This are the answer choices


1.)real, upright, smaller


2.)virtual, upright, smaller


3.)real, inverted, larger


4.)real, upright, larger


5.)virtual,inverted,smaller


6.)virtual,inverted, larger


7.)real, inverted, smaller


8.)virtual, upright larger


9.)none of these





Please explain your answer.. and if you don't know.. please don't respond.
