Answer:
The magnification of a virtual image is -0.33
Explanation:
We can calculate the magnification as the ratio of height of the image to the height of the object. It can be also stated as the ratio of size of the image obtained to the original size of the object. Also this ratio can be equated to the ratio of image distance to object distance. So magnification can be termed as ratio of image distance to object distance. As in the present case, the image distance or the distance of the formation of image from the lens is 10 cm and the distance of object from the lens or the object distance is 30 cm. Then, .
So, the image will be diminished to 0.33 times the original size as the magnification of the virtual image is obtained as -0.33.
