It depends on what the specimen is. If for example - the specimen is a person's finger-print, then low magnification is sufficient. However - if the specimen is a sample of blood, a higher magnification would be needed to show individual blood cells.
high lens
An electron microscope, specifically a transmission electron microscope, would be used to study a specimen smaller than 0.2 micrometers. This type of microscope uses a beam of electrons to create high-resolution images of tiny structures at the nanometer scale.
It depends on what magnification the ocular lens is (usually 10x), then you multiply that by the objective lens magnification (what you said to be 40x). So the microscope would magnify your specimen by 400 times.
A high-power microscope, such as an electron microscope, is used to visualize the endoplasmic reticulum. The intricate structure of the endoplasmic reticulum requires high magnification and resolution to observe its details effectively.
In a light microscope magnification is varied by using different lenses to refract the light. In an electron microscope magnification is varied by altering the configurations of magnetic fields to bend the electron beam.
multiply the magnification of the eyepiece by the magnification of the high objective lens. for example, if the eyepiece magnifies x10, and the high objective magnifies x40, then the total magnification would be 400x
---- You would use the light microscope. The electron microscope would be unnecessary in this situation, due to its high magnification levels.
The transmission electron microscope (TEM) has the highest potential magnification of any microscope, typically up to 1,000,000x. This high magnification allows visualization of structures at the atomic level.
high lens
You would typically use a high magnification objective lens, such as 40x or 100x, to see small objects with a microscope. This allows you to view the details of the object at a much larger scale than with lower magnification lenses.
The objective lens is the part of a microscope that allows for the greatest magnification. It is located at the bottom of the microscope and is responsible for gathering light and magnifying the image of the specimen. By using different objective lenses with varying magnification powers, the total magnification of the microscope can be increased.
A magnification of at least 400x is typically needed to see protists clearly under a microscope. This level of magnification allows you to observe the details of their structure and movement.
Microscopes vary in power. You can determine total magnification by the eyepiece and the lens.
The magnification of a microscope is calculated by multiplying the magnification of the objective lens by the magnification of the eyepiece. In this case, if you have a 10x low power objective and a 10x high power objective, the total magnification would be 100x (10x * 10x) for both objectives when used with the same eyepiece magnification.
you multyply the low powered objective and the high powered objective :)
An electron microscope, specifically a transmission electron microscope, would be used to study a specimen smaller than 0.2 micrometers. This type of microscope uses a beam of electrons to create high-resolution images of tiny structures at the nanometer scale.
That depends on the type of microscope you are using, so check the lab you work or go to school in. At my lab, our microscopes have 4x, 10x, 40x, 100x magnification lenses.
