Why does the field of view decrease as the power of objective lens increase?

There is a relationship between the power of an objective lens and its field of view. As the power of the objective lens increases, the size of its field of view decreases


Which objective of a compound microscope would show the largest field of view?

You use the 3 objective lenses of a compound microscope to switch powers. There's LOW, MEDIUM, and HIGH power. With LOW power, you can magnify what you're looking at. With HIGH power, you can see things that you can't see with a naked eye.


How would you estimate the size of object viewed under high power objective lens 40 times if you were given the size of the field diameter when using low power objective lens 4 times?

You can estimate the size of the object by comparing the field diameters observed under the low power objective lens (4x) and high power objective lens (40x). Calculate the ratio of the field diameters (40x/4x = 10), and use this ratio to estimate the size of the object viewed under the high power objective lens. Simply multiply the size of the object viewed under the low power objective lens by the ratio (field diameter at 4x) to get an estimation.


What is ocular lens and objective lens?

The ocular is the upper lens and objective is the lower lens


How do you calculate field diameter?

Field diameter is calculated by measuring the distance across the field of view of a microscope, then dividing that measurement by the magnification of the objective lens being used. This gives you the field diameter in micrometers.


Which objective lens should you begin with?

Start with the lowest magnification objective lens, typically 4x or 5x, as it provides a wider field of view and makes it easier to locate the specimen.

What part of the microscope might an arrow point to on a picture if it shows a cylinder that is the heart of a microscope?

The arrow would likely point to the cylinder lens, which is the objective lens of the microscope. This lens is responsible for magnifying the specimen being observed.


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.


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.


When moving from a lower objective lens to a higher objective lens why does is the image lost?

Because during movement of lens there is no slide below objective .


Is the low power objective lens the shortest objective lens?
