What would be the size of an object in mm that occupies 25 of the size of a field of view that is 32mm in diameter?

The object would be 8 mm in size. This is calculated by taking 25% of the diameter of the field of view (32 mm) which is 8 mm.


If the field of view of the low power 10x objective lens is 4 mm what would the field of view be for the oil immersion 100x lens?

The field of view of the oil immersion 100x lens would be 0.4 mm. This is because the field of view decreases as the magnification increases.


Diameter of the field of view in millimeters when using the 4X objective?

five


What will happen to the field of view as you change objectives form 4x to 10x to 40x?

As you change objectives from 4x to 10x to 40x, the field of view will decrease. This is because higher magnification objectives bring smaller areas into focus, resulting in a narrower field of view.


The diameter of a microscope's field of view is estimated to be 0.9 mm . about how wide is an object that fills two thirds of the field circle your answer?

0.6 mm


Why to start with 4x objective rather than higher power?

Starting with a 4x objective allows for a larger field of view and greater depth of field, making it easier to locate and focus on the specimen. Higher power objectives have a smaller field of view and shallower depth of field, which can make it challenging to find and keep the specimen in focus.


What objective lens shows largest field of view?

The lowest magnification objective lens, such as the 4x lens, typically provides the largest field of view because it allows more of the specimen to be visible at once. This is useful for observing larger structures or getting an overall view of a specimen before zooming in with higher magnification lenses.


Is a grid slide with 1 mm squares used to directly measure the field of view?

yes.


A unicellular organism takes up one third of the field of view at medium power what is the actuall size of the organism?

The actual size of the unicellular organism would depend on the total field of view at medium power on the microscope. Without knowing the specific magnification and field of view of the microscope, it is difficult to determine the actual size of the organism.


Why would the 4x provide the largest field of view rather than the 40x when using a microscope?

The 4x objective lens provides the largest field of view because it has a lower magnification power, allowing you to see a larger area of the specimen at once. The 40x objective lens has a higher magnification power, resulting in a smaller field of view but greater detail.


What is the difference between a 200mm lens and a 20 times lens?

It depends on the actual focal length. For a 35 mm format lens, 200 mm is about 4x magnification, to get 20x you'd need a 1000 mm lens. For smaller formats, such as 8 mm or a camcorder, find the focal length for normal view, then multiply by 20.


Does the 4x or the 10x objective have a shorter depth of field?

100x the higher the magnification the shorter the working distance
