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.
