Question
By looking at the construction of a compound microscope and a telescope, how will you distinguish which type of optical instrument is which?
✓

Answer

The aperture of the objective of a compound microscope is very small and the aperture of the telescope lens is very large. Therefore, the two types of optical instruments can be differentiated by looking at the apertures of the objective.
