The number of cells in a field of view (FOV) with a 4X objective lens can vary depending on the microscope's specifications and the size of the cells being observed. Generally, a 4X objective provides a wide field of view, allowing you to see a larger area, which may typically encompass hundreds to thousands of cells. To determine the exact number, you would need to calculate the FOV size based on the microscope's parameters and estimate how many cells fit within that area.

Magnification is inversely proportional to the diameter of the field of view.

At low power on the compound microscope, the diameter of the field of view is 4 millimeters. This is reduced to 1.7 millimeters when you switch to medium power and further reduced to 0.4 millimeters when you switch to high power. Covert the measurment for the field of view from millimeters to microns, the conventional unit of measurment in microscopy. There are 1000 microns in one millimeter. Low power: 4mm= 4,000um Medium power: 1.7mm= 1,700um High power: 0.4mm= 400um
Scanning a specimen using a low-power objective allows you to observe the greatest number of cells within the field of view. Low-power objectives have a lower magnification but a wider field of view compared to high-power objectives, enabling a broader view of the specimen.

Depending on how many cells there are in the field of view. On medium power, you may not be able to see any.
To determine how many pith cells would fit across the diameter of a low-field microscope view, we first need to know the average size of a pith cell, which is typically around 0.1 to 0.5 mm in diameter. Low-field microscopes usually have a field of view diameter ranging from about 1 mm to 5 mm. Therefore, depending on the size of the pith cells and the specific field of view, approximately 2 to 50 pith cells could fit across the diameter of the microscope's view.
1,600 (micrometers {microns} per one field of view) divided by 40 (cells per field of view) equals [units cancel] 40 microns per cell.
To find the width of each cell in micrometers, divide the diameter of the field by the number of cells counted. (1.6 mm / 40 cells = 0.04 mm per cell ). Convert to micrometers by multiplying by 1000: (0.04 mm * 1000 = 40 μm). Therefore, each cell is 40 micrometers wide.
Cats generally have better vision than dogs. They have a wider field of view and better night vision due to a higher number of rod cells in their eyes.
A bright field microscope can be used to view stained samples that absorb light, making them appear darker against a bright background. It is commonly used in biology labs to view cells, bacteria, and tissue samples.

In a 40X magnification, you may be able to see around 10-15 red blood cells in a small field of view under a light microscope. The exact number can vary depending on the microscope and the specific sample being observed.
