Problem 50
Q

An inexpensive instructional lab microscope allows the user to select its objective lens to have a focal length of 32 mm, 15 mm, or 3.9 mm. It also has two possible eyepieces with magnifications 5×5\times and 15×15\times. Each objective forms a real image 160 mm beyond its focal point. What are the largest and smallest overall magnifications obtainable with this instrument?

A
Mmin=25×,Mmax=620×M_{min} = 25\times, M_{max} = 620\times
