Question

In an astronomical refracting telescope, the final image formed by the eyepiece is:

Options

• Virtual and magnified

• Real, erect, and diminished

• Real and inverted on the retina directly

• Always of the same size as the object

Answer 1

The objective lens forms the image at its focus, and this image acts as the object for the eyepiece. The eyepiece forms the final virtual, magnified image, which is what the observer sees when looking through the telescope.
