Question

The mirror equation relates the object distance, d₀_, the image distance, d_i, and the focal length, f, of a mirror as

1 / d₀ + 1 / d_i = 1 / f
While in other topics, distance and length are strictly non-negative, in optics we introduce the following sign conventions:

Object distance is positive for a real object and negative for a virtual object.
Image distance is positive for a real image and negative for a virtual image.
Focal length is positive for a converging mirror and negative for a diverging mirror

(a) Select the best choice to complete this statement. A real object placed in front of a converging mirror creates a real image

under all circumstances.
under no circumstances.
when the object is between the focal point and the mirror.
when the object is farther than the focal length from the mirror.

(b) Select the best choice to complete this statement. A real object placed in front of a diverging mirror creates a virtual image

under all circumstances.
under no circumstances.
when the object is between the focal point and the mirror.
when the object is farther than the focal length from the mirror.

under all circumstances.
under no circumstances.
when the virtual object is farther than the focal point.
when the virtual object is closer than the focal point.
