TRUE OR FALSE

The virtual image formed by a convex mirror is always enlarged.
A convex mirror never forms a real image of a real object.
When the object of a concave mirror is inside the focal point, the image is virtual.
The image produced by a convex mirror is always closer to the mirror than it would be in a plane mirror for the same object distance.
A concave mirror always forms a virtual image of a real object.
A virtual image formed by a concave mirror is always enlarged.
A concave mirror always forms an enlarged real image of a real object.

    what are your ideas on this?

    hint: it depends on the distance of the object from the mirror.

    All answers are correct. The next-to-last required a bit of thinking.
    1/do must be less than 1/|di| if di is negative (virtual). You also know that f is positive. Therefore
    1/do - 1/f = 1/|di|
    Therefore 1/do < |1/|di| ;
    |di| > do so the image is enlarged.
