Question
What is the unit of measurement of magnification?
- m
- D
- It is unitless
- cm
Hint:
Magnification is a measurement or the ratio of two lengths, so it has no units.
The correct answer is: It is unitless
Magnification is unit less.
- The magnification is a dimensionless constant.
- It is the ratio of the image height and object height.
- Since a dimensionless constant has no unit. So the magnification has no unit.
- Thus, magnification is a ratio of two lengths, so it is unitless.
