State the meaning of magnification in spherical mirrors. How is it related to object distance and image distance? When is magnification positive or negative?
Answers
Hey!!!
1.Magnification is the increase in the image size produced by spherical mirrors with respect to the object size... It is the ratio of the height of image to the height of object and is denoted as m..
2.The magnification m produced by spherical mirrors can be expressed as :m=h'h where h is height of image and h is height of object.. It is also equal to the negative of the ratio of the image.distance (v) to object distance (u) m=vu..
According to convention object distance is always negative..
3.A magnification of 1 (plus or minus) means the image is the same size as the object.. If the magnification is positive, the image is upright compared to the object; if m is negative, the image is inverted compared to the object ...
I really hope it will helpful ☺️
