Question 30: NCERT Solutions for 12th Class Physics: Chapter 9-Ray Optics and Optical Instruments
(a) At what distance should the lens be held from the figure in previous question in order to view the squares distinctly with the maximum possible magnifying power?
(b) What is the magnification in this case?
(c) Is the magnification equal to the magnifying power in this case? Explain.
(a) For maximum magnifying power the image should be at least distance of distinct 1 vision i.e., 25 cm.
(b) Linear magnification in the situation of maximum magnifying power.
(c) Maximum magnifying power in the same situation
So, it can be observed that in the situation when image is least distance of distinct vision the angular magnification and linear magnification have similar values.
