Focal point of image in magnifying glass

In summary, the focal point of the image in a magnifying glass is not a real image, but a virtual image that appears smaller than the actual object.

focal point of image in magnifying glass

--------------------------------------------------------------------------------
I have been given a statement and have to decide if it is true or false and then justify my answer.
I have already established that this statement is false by the fact that a magnifying glass
creates a 'virtual image' not a 'real' one but i am having trouble working out what else is false about it.

ok here's the statement;

In the normal use of the magnify, the object is placed within the observer's near point distance and a real image is produced between the observers near point and infinity. This image subtends a greater angle at the observers eye than does the object in its position between the near point and the eye.

any help would be much appreciated

This statement is false because a magnifying glass does not produce a real image. A magnifying glass produces a virtual image that appears to be behind the lens, rather than in front of it. Therefore, the image subtends a smaller angle at the observer's eye than the object itself.
 

What is the focal point of an image in a magnifying glass?

The focal point of an image in a magnifying glass is the point at which the light rays passing through the lens converge and form a clear and magnified image. It is the point where the image appears the largest and the most focused.

How is the focal point of an image determined in a magnifying glass?

The focal point of an image in a magnifying glass is determined by the curvature and thickness of the lens. The shape and size of the lens determine how the light rays are refracted and where they converge to form the focal point.

What happens if the object is placed outside the focal point of a magnifying glass?

If the object is placed outside the focal point of a magnifying glass, the image will appear smaller and the image may appear distorted or blurred. This is because the light rays are not converging at the correct point to form a clear and magnified image.

Can the focal point of a magnifying glass be changed?

Yes, the focal point of a magnifying glass can be changed by adjusting the distance between the lens and the object. Moving the object closer to the lens will result in a shorter focal length and a larger magnification, while moving the object further away will result in a longer focal length and a smaller magnification.

What is the difference between the focal point and the focal length in a magnifying glass?

The focal point is a specific point where the light rays converge to form a clear and magnified image. The focal length, on the other hand, is the distance between the lens and the focal point. It is a measure of how much the light rays are bent by the lens and determines the level of magnification.
