Question

Explain the 1st focal point of convex lens of an image when the object is at 2F and F​

Answer 1

Explanation:

The ray diagram above illustrates that when the object is located at a position beyond the 2F point, the image will be located at a position between the 2F point and the focal point on the opposite side of the lens. Furthermore, the image will be inverted, reduced in size (smaller than the object), and real.
