An object is placed at different distances, u, from a converging lens of focal length, 15.0cm. For what value of u does the lens act as a microscope?
u = 15cm only
u = 30cm only
M < 15cm only
u > 30cm only
설명
For a converging lens to act as a simple microscope, the object must be placed at a distance less than one focal length.
