Chapter 18.2, Problem 28SSC

To determine

The charactimage of the image for object 1 and object 2.

Answer to Problem 28SSC

The image formed by both object 1 and object 2 is a reduced, upright and virtual image.

Explanation of Solution

Given:

The given ray diagram is shown below.

  

Concave lens is thin at the centre and thick at the edges. This surface of the lens curve inwards. The concave diverge the light rays falling on it.

Consider the givne ray diagram. The focus of the concave lens is denoted by F.The object 1 is placed between F and 2F.The object 2 is placed between the lens and F.The image formed by concave lens is always virtual, erect and diminished image regardless of how far the object is placed from the lens.Hence, the image formed by both object 1 and object 2 is a reduced, upright and virtual image.

Conclusion:

Thus, the image formed by both object 1 and object 2 is a reduced, upright and virtual image.
