The magnification of a virtual image is 2. Magnification is defined as the ratio of image distance to object distance.
Magnification is the ratio of the image distance to the object distance.
The given data in the problem is;
Image distance (u) = 10 cm
Object distance (v) = 20 cm
The magnification of a virtual image is;
m=v/u
m=20/10
m=2
Hence the magnification of a virtual image is 2.
