Consider the following statements about images formed by several optical instruments.(A) The images formed by plane mirrors are always virtual, upright and equal in height of the object.(B) The images formed by concave lenses are always virtual, upright and smaller than the object.(C) Images formed by convex lenses are either real or virtual as well as inverted or upright.
Question
Consider the following statements about images formed by several optical instruments.(A) The images formed by plane mirrors are always virtual, upright and equal in height of the object.(B) The images formed by concave lenses are always virtual, upright and smaller than the object.(C) Images formed by convex lenses are either real or virtual as well as inverted or upright.
Solution
The statements provided are all correct.
(A) Plane mirrors always form images that are virtual, upright, and the same size as the object. This is because the light rays never actually converge, they only appear to do so behind the mirror.
(B) Concave lenses also form images that are virtual, upright, and smaller than the object. This is because concave lenses diverge light rays away from a point, making the image appear as if it's coming from a point closer to the lens than the object actually is.
(C) Convex lenses can form both real and virtual images, and these can be either inverted or upright. This depends on the position of the object in relation to the lens. If the object is further away from the lens than the focal point, the image will be real and inverted. If the object is closer to the lens than the focal point, the image will be virtual and upright.
