Question

# Which of the following is correct?

- vh = uH
- uh = vH
- vuh = H
- vh = uvH

Hint:

**Magnification** can be calculated as **m= H/h=v/u**

## The correct answer is: vh = uH

### vh/uH is correct.

- Magnification in the terms of the height of the object and image can be written as H/h where H is the height of the image and h is the height of the object.
- The m= v/u, where, v= image distance and u= object distance
- Thus, the height of the image and object with reference to the distances of the image and object can be written as vh/uH.
