Question
An object is placed 8.0 cm from a thin converging lens of focal length 5.0 cm. Which statement about the image formed by the lens is correct?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Using the lens formula: 1/f = 1/u + 1/v. u = 8 cm, f = 5 cm. 1/5 = 1/8 + 1/v => 1/v = 1/5 - 1/8 = 3/40 => v = 40/3 = 13.33 cm (positive, so real). Magnification m = -v/u = -13.33/8 = -1.67 (negative, so inverted). The image is real and inverted.
Hint
Use the lens formula. A positive image distance (v) means a real image.
