A transmission electron microscope (TEM) is used to examine thin slices of specimens that are typically less than 100 nanometers thick. This type of microscope can provide ultra-high resolution images by passing electrons through the specimen to create detailed images of the internal structures.

Can live specimens be used in a TEM microscope?

Live specimens cannot be used in a transmission electron microscope (TEM) as the high vacuum environment and electron beam would quickly kill any living cells. Instead, biological specimens must be fixed, dehydrated, and stained prior to imaging in a TEM.


Why must a specimen be thin in order to be viewed under the microscope?

Specimens must be thin in order to be viewed under the microscope because light can only pass through a certain thickness of material. A thin specimen allows light to pass through and interact with the cells, allowing the microscope to produce a magnified image. Thicker specimens would prevent light from passing through and produce a blurry or unreadable image.


Why must specimens viewed with a compound microscope be thin why are they sometimes stained with dyes?

Specimens viewed with a compound microscope need to be thin to allow light to pass through and be focused by the lenses. Staining with dyes increases contrast and visibility of certain structures within the specimen by highlighting specific parts of the sample. This helps to distinguish different components and makes them easier to observe under the microscope.


What is the basic requirement for you to see an object using the microscope?

The basic requirement for you to see an object using the microscope is light. The amount of light will determine the visibility of the specimen.


Why must a specimen be thin to be viewed under the microscope and why are they sometimes stained with dyes?

Specimens need to be thin to allow light to pass through and enable clear visualization under the microscope. Staining with dyes helps to highlight specific structures or components within the specimen, making them easier to observe and distinguish.

Why must specimens viewed with a compound microscop be thin?

Specimens viewed with a compound microscope must be thin to allow light to pass through them. This ensures that the light rays can illuminate and pass through the specimen, which is necessary for magnifying the image and producing a clear view under the microscope. Thicker specimens would scatter or block the light, resulting in a blurry or dark image.

Why might a microscopist who specializes in the use of microscopes to examine specimens use a light microscope instead of an electron microscope?

An electron microscope requires that the subject be dead to function. In order to receive a picture, the specimen must be coated in chemicals and put into a vacuum, a process which will kill any living specimen. A light microscope, although not as detailed, will allow the scientist to observe living specimens.

For a microscope to be useful it must combine two properties?

For a microscope to be useful, it must have both high resolution and magnification capabilities. High resolution allows for clear image quality and detail, while magnification enables viewing of small objects or structures at a larger scale. Combining these two properties provides a powerful tool for studying and analyzing microscopic specimens.

Why a specimen need to be viewed under the microscope must be thin?

Specimens need to be thin to allow light to pass through them and be able to observe details and structures at a cellular or subcellular level. Thicker specimens would block the light and hinder the ability to visualize the specimen clearly under a microscope. A thin specimen also helps to reduce scattering and distortion of the image.


Why must the prepared specimen for a monocular microscope be very thin?

A thin specimen allows light to pass through easily, resulting in clearer and sharper images under the microscope. Thicker specimens can distort the light and make it more difficult to observe the details of the sample.


How do you write microscope in a sentence?

I must have left my microscope in the car.


Why is the specimen prepared for a monocular microscope must be very thin?

The specimen must be very thin for a monocular microscope because light has difficulty passing through thick specimens, leading to poor image quality and decreased clarity. A thin specimen allows more light to pass through, resulting in a sharper and more focused image when viewed through the monocular microscope.
