Explanation / Answer
(6) Here Object distance is : 81.25 -27.0 cm u` = 54.25 cm Focal length (f ` ) = - 67.0 cm We have : 1 / f ` = 1/ u` + 1/ v` or 1/ v` = 1/ f ` - 1 / u` = - 1 / 67.0 - 1 / 54.25 New Image location is : v` = - 29.977 cm ˜ - 30 cm (7) Magnification (M `) = - v` / u` = 30.0 / 54.25 = 0.553 Hope this helps u!Related Questions
