Concept explainers
Tape a picture of yourself on a bathroom mirror. Stand several centimeters away from the mirror. Can you focus your eyes on both the picture taped to the mirror and your image in the mirror at the same time? So where is the image of yourself?
Answer to Problem 1CQ
Explanation of Solution
The image formed in a flat mirror will be on the mirror surface even the person is near the mirror or away from the mirror. Only the size of the image decreases with the increase in distance between the person and object. However, the person can only focus on the one image at a time and the final image will be smaller compared to the initial.
Conclusion:
No, a person cannot focus on different images at a time.
