Question

Explain the nature of the image formed by a magnifying glass.

Answer 1

Magnifying glass:

1. A magnifying glass is a convex lens used to make an object appear much larger than it actually is.
2. This works when the object is placed at a distance less than the focal length from the lens.
3. A magnifying glass uses a convex lens because these lenses cause light rays to converge, or come together.
4. Hence, by applying the properties of a convex lens we can state:

The image is:

1. upright (the right way up)
2. magnified (larger than the object)
3. virtual (cannot be produced on a screen)

Hence, a magnifying glass produces a virtual and erect image.
