the magnification produced by a lens is (-1). what does this mean?
Answers
if magnification is in negative means image form by lens is real and inverted and concave lens can't form this so this lens is convex and magnification is -1 means image hight and object hight is same (m=Hi/Ho) so this is possible when object kept on center of curvature (c)
Answer:It refers to linear manification of the image produced by the mirror.
Linear magnification = height of image/height of object = image distance/object distance. (The distances are measured from the pole of the mirror)
It is given that the magnification is -1
Therefore, height of image/height of object = -1
It means that the height of image is same as the height of object.
It means there is no magnification of the image compared to the object
The positive sign indicates that the image and the object are erect. If the magnification is indicated by - sign, the object is erect but the image is inverted.
