Question

Rank the image descriptions in the order that you would observe them if you were to move an object from very far away from a converging lens to very near it. Rank the image descriptions in the order you would observe them, starting with the object far from the lens and ending with the object very near the lens.

Answer 1

1. The image is vanishingly small and near the focal point: - object beyond \(2 \mathrm{f}\)

2. The image is real and inverted: - object at \(2 \mathrm{f}\)

3. The image is infinitely large and infinitely far away: - object between \(2 \mathrm{f}\) and \(\mathrm{f}\)

4. The image is virtual and upright: - object at \(\mathrm{f}\)
