by focus and magnification
Yes, the wavelength of the light limits the maximum magnification of a microscope. Using visible light, the limit is about 1200 to 1500X.

Magnification in a microscope refers to the ability to make an object appear larger than its actual size. It is primarily achieved through the objective lens, which gathers and focuses light to magnify the specimen. The total magnification is a combination of the magnification of the objective lens and the eyepiece.
The total magnification of a light microscope is determined by multiplying the magnification of the objective lens by the magnification of the eyepiece. However, this doesn't mean the total magnification capability is unlimited, as there are practical limitations to both lens magnification and optical resolution. Beyond a certain point, increasing magnification can lead to a decrease in image quality and clarity.
Early light microscope
Yes, compound microscopes use light for illumination. Light is typically directed through the specimen being observed to enable magnification and visualization of the object on the slide. The light source can be built into the microscope or come from an external source.
A compound microscope uses 2 lenses (objective lens and eyepiece lens) along with a light source to magnify and view samples at high magnification.
An electronic microscope's strength depends on if it's a light microscope or an electron microscope. A light microscope can only perform a few thousand times magnification but an electron microscope can go into many hundreds of thousands of times magnification.
The smallest magnification lens on a compound light microscope is the scanning objective lens, typically with a magnification of 4x.
The magnification of a compound light microscope is determined by multiplying the magnification of the ocular lens (eyepiece) by the magnification of the objective lens. For example, if the ocular lens has a magnification of 10x and the objective lens has a magnification of 40x, the total magnification would be 10x * 40x = 400x.
An electron microscope achieves the highest magnification and greatest resolution among microscopes. This type of microscope uses a beam of electrons instead of light to create an image, allowing for much higher magnification and resolution than light microscopes.
It
To set up a microscope follow these steps:Hold the microscope by its base.Place it near a light source. (Not directly in the sun.)Adjust the mirror until light is reflected up the microscpe. (Check this by looking done the microscope.)Turn the objective lens to its lowest magnification.
Actual magnification of light microscopes could reach up 1000x magnification depending on the type of light microscope. Light microscopes could be divided into brightfield microscope and phase-contrast microscope for viewing stained specimen and unstained specimen respectively. Magnification of electron microscope on the other hand could go up to 1000000x. The actual magnification as well depends on types of electron microscope which includes transmission-electron microscope and scanning-electron microscope where both of them are used in viewing internal cell structures and cell surface structures respectively.
A light microscope can be used to view both live and dead samples. The range of magnification for a light microscope typically falls between 40x to 1000x, depending on the specific lens and microscope configuration.
The mirror or a light source reflects the light onto the specimen placed on the stage of a microscope. The objective lens then focuses this light on the specimen, allowing for magnification and visualization.
