Question
An image of height 4 m is formed by a convex lens of an object of height 2 m. The magnification is _____.
Hint:
The magnification of a convex lens is the ratio of the object distance to the image distance
The correct answer is: 2
An image of height 4 m is formed by a convex lens of an object of height 2 m, the magnification is 2
- The magnification of an image can be measured using m= v/u.
- The u is the object distance whereas the v is the image distance.
- Hence, magnification m= 4/2 =2
