Correct option is C
The correct answer is: (C) Both (a) and (b)
Only real images can be projected onto a screen.
Real images are formed when light rays actually converge after reflection/refraction.
Real images can be enlarged (e.g., object placed between focus and center of curvature of concave mirror) or diminished (e.g., object placed beyond the center of curvature).
Virtual images cannot be captured on a screen because the rays only appear to meet; they do not actually converge.
Information Booster:
Virtual images are always erect and cannot be obtained on a screen.
Concave mirrors and convex lenses can produce both real and virtual images.
Convex mirrors and concave lenses always produce virtual, diminished, and erect images.
Real images are always inverted, and can be either enlarged or diminished depending on object distance.
Virtual images are formed by diverging rays, and only seen with eyes or sensors (not on a screen).
Additional Information:
(a) Real and enlarged – seen when object is placed between F and C in concave mirror.
(b) Real and diminished – seen when object is beyond C in concave mirror.
(c) Virtual and enlarged – seen with magnifying glasses (convex lens), but not on screen.
(d) Virtual and diminished – produced by convex mirrors and concave lenses, not screenable.
