Question
Which of the following is a formula to measure the magnification produced by a lens?
- v/u
- -v/u
- u/v
- -u/v
Hint:
Magnification (m) for a lens= Image height/object height or Image distance/ object distance
The correct answer is: v/u
The formula to measure the magnification produced by a lens is v/u.
- The magnification of a lens can be calculated as the ratio of image height to object height (hi/ho).
- When the distance of the image is v and object distance is u, the magnification formula for lens will become v/u (hi/ho).
