Q11MCell StructureFree sample

A light microscope is used to observe two membranes that are $200\text{ nm}$ apart.

How far apart are the membranes when the objective lens is changed from low power ( $\times 40$ ) to high power ( $\times 400$ )?

Options

A $2\text{ µm}$
B $20\text{ µm}$
C $200\text{ nm}$
D $2000\text{ nm}$
