Question
An image of an object located at infinity was formed by a concave lens. The magnification of the image _____.
- Is greater than 1
- Is less than 1
- Is negative
- Tends to 0
Hint:
For a concave lens, magnification of the image depends on the size and position of the object.
For an object located at infinity, formed by a concave lens, a virtual and erect, highly diminished(size tend to zero), point sized image is formed.
The correct answer is: Tends to 0
If an image of an object located at infinity was formed by a concave lens, the magnification of the image tends to zero.
- In a concave lens, magnification of the image depends on the size and position of the object.
- The image formed on the opposite side shows a magnified view.
- The magnification of the image kept at infinity distance in a concave lens will tend to zero.
