Question

For a convex lens to produce a real, enlarged, inverted image which of the following must be true?1) The object’s distance must be greater than one focal length but less than twice the focal length.2) The object’s distance must be greater than twice the focal length.3) The object’s distance must be equal to the focal length.4) The object’s distance must be less than one focal length.

Answer 1

For a convex lens to produce a real, enlarged, and inverted image, the following must be true.

The object's distance must be between F and 2F.

In other words, the object’s distance must be greater than one focal length but less than twice the focal length.

Therefore, the 1st option is the correct answer.

"The object’s distance must be greater than one focal length but less than twice the focal length."
