A student uses a light microscope to study plant cells.
One of the cells drawn by the student is shown in Fig. 16.1.
Fig. 16.1
The actual length of this plant cell is 0.15 mm0.15\text{ mm}0.15 mm.
Calculate the magnification of the student's drawing.
Use the equation: magnification=measured size÷actual size\text{magnification} = \text{measured size} \div \text{actual size}magnification=measured size÷actual size
Magnification = × \times× ** **
