A student wants to calibrate an eyepiece graticule to measure the dimensions of plant cells under a light microscope.
Which option correctly identifies the device that must be placed on the stage of the microscope for this calibration, and the change that would require the graticule to be recalibrated?
Device on stage: Stage micrometer; Change requiring recalibration: Changing the magnification of the objective lens.
Device on stage: Stage micrometer; Change requiring recalibration: Changing the light intensity.
Device on stage: Eyepiece graticule; Change requiring recalibration: Changing the magnification of the objective lens.
Device on stage: Eyepiece graticule; Change requiring recalibration: Changing the stage height focus.
