Frequently Asked Questions

Why does an image get larger as an object moves closer to the focal point of a magnifying glass?

As the object approaches the focal point, the image distance increases rapidly (from the lens equation), and magnification m = v/u increases. When the object reaches the focal point, the image becomes infinitely large and is at infinity.

Can a diverging lens ever form a real image?

No. A diverging lens always forms a virtual image regardless of object position. The diverging rays never actually converge, so no real image is possible.

What is the difference between a microscope objective and an eyepiece?

The objective lens forms a real, magnified image of the specimen. The eyepiece acts as a magnifying glass, producing a virtual image of the real image formed by the objective. Total magnification is the product of both lens magnifications.
