Chapter SH, Problem 13.1APP

To determine

To calculate: Distance between the lens and the object.

Answer to Problem 13.1APP

Distance between the lens and object should be less than $\underset{\_}{5\text{ cm}}$ .

Explanation of Solution

Given:

Focal length of convex lens = $5\text{ cm}$

Image formed is virtual, enlarged and upright.

Calculation:

For the image formed by a convex mirror to be virtual, enlarged and upright, the object is less than one focal length from the lens.

Hence, distance between the lens and object should be less than $5\text{ cm}$ .

Conclusion:

Distance between the lens and object should be less than $\underset{\_}{5\text{ cm}}$ .
