Questions

Describe the general orientation and magnification of the images formed through the convex lens before the image became blurry (this occurs when the image distance is larger than the distance from the lens to your eye).

What kind of image forms through the convex lens in the above situation, and how do you know?

How does the image of the window appear through the lens at this distance? What kind of image is this, and how do you know?

At what distance must you position the screen in order to view a clear image on the paper?

Solution

Position of the object Position of the image Nature of the image Size of the image Between O and F1 on the same side of the lens Erect and virtual Magnified At 2F1 At 2F2 Inverted and real Same size Between F and 2F1 Beyond 2F2 Inverted and real Magnified At F1 At infinity Inverted and real (image gets blurry) Magnified Beyond 2F1 Between F2 and 2F2 Inverted and real Diminished At infinity At F2 Inverted and real Diminished
