GENERAL HISTOLOGY

Detailed explanation-1: -When you switch to a higher power, the field of view is closes in. You will see more of an object on low power. The depth of focus is greatest on the lowest power objective. Each time you switch to a higher power, the depth of focus is reduced.

Detailed explanation-2: -OCCURS BECAUSE IN LOWER POWER YOU HAVE A WIDER FIELD OF VIEW AND WHEN YOU SWITCH TO A HIGHER POWER IT NARROWS YOUR VIEW AND IT BECOMES OUT OF FOCUS WHICH DOES NOT HELP. WAYS TO PREVENT IS: CENTER THE OBJECT YOU WANT TO VIEW AS MUCH AS POSSIBLE BEFORE SWITCHING TO A HIGHER POWER AND INCREASE MAGNIFICATION SLOWLY.

Detailed explanation-3: -In a microscope, low power indicates lower magnification and high power indicates higher magnification. The high power, higher magnification setting decreases the field of view of the microscope. That is, the area that the microscope can image becomes smaller.

Detailed explanation-4: -The field of view is inversely proportional to the magnification power, meaning that as the magnification increases, the field of view decreases. As such, when the magnification is increased from 4x to 40x, the field of view decreases.

Detailed explanation-5: -Answer and Explanation: The field of view gets smaller as you progress from a low power objective to a higher power objective. The field of view is the area that is observable when looking into a microscope through the oculars.
