Question

can we watch our virtual image in a concave mirror(even when we keep the mirror beyond focus)?

if yes show a ray dia of the same if no then how can we see our image in the concave side of a spoon(beyond spoon)

Answer 1

No, if the position of the object is beyond focus, then the image will always be real and inverted. A spoon has two surfaces. First is concave and the second one is convex. Thus, it acts both as a concave and a convex mirror. Thus if we see our face on the concave surface, a real and inverted image is formed.. It is so because spoon is small in aperture and the focal length is also very small.
