Question

In which of the following the final image is erect?
(a) Simple microscope
(b) Compound microscope
(c) Astronomical telescope
(d) Galilean telescope

Answer 1

Simple microscope forms an erect image

Explanation:

The image formed by the Compound microscope and Astronomical telescope is inverted,but in case of Simple microscope,Convex lens with a small focal length is used when a very small object is placed within its focus, a virtual, erect and magnified image of the object is formed at minimum distance of distinct vision from the eye held near to the lens.

Answer 2

Answer is Options (a) & (d)

Explanation:

(a) Simple microscope

(d) Galilean telescope

• A virtual Image is formed in a simple microscope and that too on same side of object above axis.  

Whereas A virtual but magnified and erect image which lies is in between the Eyepiece & Objective lens.

Coming on to Astronomical Telescope as well as Compound Microscope, both believe in producing images which are inverted.
