The Second Edition of the Oxford English Dictionary is currentlyavailable as a 20-volume print edition and costs $895. Imagine thatthe publishers would like to distribute a lower-cost version of thedictionary that still contains all of the same words, but in asmaller number of volumes. To accomplish this, they decide toreduce the font size to 1/3 of the original font size and include asimple biconvex single-lens magnifier with the new reduced-volumeset. (a) Fully specify a design for the required single lensmagnifier. (b) If the publishers had wanted to severely reduce thefont size to 1/15 of the original size, could they still supply asingle-lens magnifier for the customers to use? Specify a designfor such a magnifier and identify any physical and/or opticalperformance limitations that arise. What is the maximum diameterpossible for this magnifying lens?
