Question
If you are told an image has been made by a single optic (either a lens or a mirror) that has a positive focal length, which of the following must be true? Choose all that apply.
The image is real.
The image is virtual.
The image has a positive image distance.
The image has a negative image distance.
The image is inverted.
The image is upright.
The image was made with a converging optic.
The image was made with a diverging optic.
If the optic is a lens, it is convex.
If the optic is a lens, it is concave.
If the optic is a mirror, it is convex.
If the optic is a mirror, it is concave.
Explanation / Answer
Here,
for a single optic with positive focal length
image can be both real or virtual depending on the object distance
as the image is real or virtual , it can be both inverted or upright
the only thing that for sure under all conditions is
that the optic is converging
hence , the true choice is
the image was made with a converging optic
and
If the optic is a lens, it is convex.
If the optic is a mirror, it is concave.
