Question

A compound microscope has on objective
with a focal length of 10mm and a tube 232
mm long. The final images is produced
250mm fromt the eye-piece when the object
is 10.5 mm from the objective. What is the
angular magnification?​

Answer 1

Answer:As the object is brought from a far off point to the focus, the

magnification goes on increasing. The apparent size of an

object depends on the angle subtended by it at the eye.Thus,

the closer the object is to the eye, the greater is the angle

subtended and larger appears the size of the object  .

The maximum size of an object as seen by

naked eye is obtained when the object is placed at the

least distance of distinct vision. For lesser distance, the

image formed looks blurred and the details of the object

are not visible.
