Question
The angular magnification of a system is less than one. Does it mean that the image formed is inverted?
✓
Answer
No, angular magnification is the ratio of the angle subtended by the final image on the eye to the angle subtended by the object on the unaided eye. Its value less than one signifies reduction in the size of the image. It does not mean that the image is inverted.
