Question
Identify as True or False the following statements concerning images formed by a SINGLE OPTICAL ELEMENT.
The element may be a plane mirror, a concave mirror, a convex mirror, a converging lens, or a diverging lens.
The image by a convex mirror or by a diverging lens is always shorter than the object.
Real images are always larger than objects.
Virtual images can be inverted (i.e., of the opposite vertical orientation as the object which formed it).
A lens creates a real image on the same side as the object.
The virtual image by a mirror is always on the side opposite the object.
Real images are always inverted (i.e., of the opposite vertical orientation as the object).
Explanation / Answer
The image by a convex mirror or by a diverging lens is always shorter than the object. :- FALSE
(in cases like u=less than f. Image is large.)
Real images are always larger than objects. :- FALSE
(in cases like u=2f or u=centre of curvature. Image is equal height of object)
Virtual images can be inverted :- FALSE
(virtual images are always upright formed by a SINGLE OPTICAL ELEMENT.)
A lens creates a real image on the same side as the object. :-FALSE
(lens creates a real image on opposite side of lens because Real images are those where light actually converges. And light always actually converge at opposite side of lens.
The virtual image by a mirror is always on the side opposite the object.:- TRUE
( virtual images are locations from where light appears to have converged & on same side of mirror light actually converge or diverge & on opposite side it appears to converge & diverge)
Real images are always inverted:- TRUE
