Question

Write two characteristics of image formed when an object is placed between the optical centre and focus of a thin convex lens. Draw the graph showing variation of image distance v with object distance u in this case.

Comments

The graph will be like a rectangular hyperbola... Isn't it?

yes......

Answer 1

Characteristics of image

1. Virtual

2. Erect

3. Enlarged

\(\frac{1}{f}=\frac{1}{v}-\frac{1}{u}\)

Answer 2

Two characteristics- virtual and enlarged image and same side of object.

As u and v both negative, we get \(\frac{1}{v}=\frac{1}{u}-\frac{1}{f}\) 

Interpret y=mx+c ,plot of the graph

Answer 3

Two characteristics- virtual and enlarged image and same side of object.
