Problem: A student makes a microscope using an objective lens and an eyepiece.If she moves the lenses closer together, does the microscope's magnification increase or decrease?a) The magnification of a microscope is M = - (L × 25cm)/(fofe) so decreasing the tube length L (while leaving fe the same) would increase the magnificationb) The magnification of a microscope is M = - (L × 25cm)/(fofe) so decreasing the tube length L (while leaving fe the same) would decrease the magnificationc) The magnification of a microscope is M = -(fofe)/(L × 25cm) so decreasing the tube length L (while leaving fe the same) would decrease the magnification.d) The magnification of a microscope is M = -(fofe)/(L × 25cm) so decreasing the tube length L (while leaving fe the same) would increase the magnification.

Magnification in a two-lens microscope:

M=mobjMeye=-(Lfobj)(25cmfeye)

The length L of the microscope is equal to the distance from the objective lens to the eyepiece.

Problem Details

A student makes a microscope using an objective lens and an eyepiece.

If she moves the lenses closer together, does the microscope's magnification increase or decrease?

a) The magnification of a microscope is = - (L × 25cm)/(fofe) so decreasing the tube length L (while leaving fe the same) would increase the magnification

b) The magnification of a microscope is = - (L × 25cm)/(fofe) so decreasing the tube length L (while leaving fe the same) would decrease the magnification

c) The magnification of a microscope is M = -(fofe)/(L × 25cm) so decreasing the tube length L (while leaving fe the same) would decrease the magnification.

d) The magnification of a microscope is M = -(fofe)/(L × 25cm) so decreasing the tube length L (while leaving fe the same) would increase the magnification.
