- A. Text becomes blurred and magnification reduces
- B. Text becomes more focussed and magnification reduces
- C. Text becomes more focused and magnification increases
- D. Text becomes blurred and magnification increases
Step-by-step solution
A magnifying glass is a convex lens. When the object is within the focal length, a virtual, erect, and magnified image is formed. As the lens is moved away from the newspaper (object distance increases), the magnification increases because the image distance also increases. However, the image may not be at the eye's near point, causing the text to appear blurred.
