Question
In which of the following the final image is erect?
  1. Simple microscope.
  2. Compound microscope.
  3. Astronomical telescope.
  4. Galilean telescope.

Answer

  1. Simple microscope.
  2. Galilean telescope.

Explanation:

In a simple microscope, the image formed is virtual and above the axis on the same side of the object. Similarly, in a Galilean telescope, the image formed is virtual, erect and magnified and between the objective lens and the eyepiece. A compound microscope and an astronomical telescope produce inverted images.
