Question
The magnification produced by a concave lens is ____.
- Is always less than 1
- Is always greater than 1
- Is always equal to 1
- Is always negative
Hint:
Concave lenses always produce upright, virtual images that are reduced in size, and located on the object's side of the lens.
The correct answer is: Is always less than 1
The magnification produced by a concave lens is less than 1.
- The magnification in any lens is the ratio of the height of the image to the height of the object.
- The image size will be always reduced in a concave lens.
- So the magnification is always less than one.
