Q15DQ
Question
How could you very quickly make an approximate measurement of the focal length of a converging lens? Could the samemethod be applied if you wished to use a diverging lens? Explain.
Step-by-Step Solution
Verified Answer
No,the same method not applied.
1Step 1: Definition of focal length
The term focal length may be defined as the distance between the center of mirror and its focus.
2Step 2: Explain reason of question
The distance between the paper and the lens is the focal length of the lens. The diverging lens virtual image cannot focus onto a piece of paper.
