Such an image can never be formed on a screen, but can be located by the method of no parallax
When is an image formed in a concave mirror virtual? This when is it real?
Virtual: if the object is inside or at the focus of the mirror
Réal: if the object is outside the focus
What does light from a distant object arrive as
A beam of parallel light
Nature, location, + size of images in convex mirrors
