A light microscope that makes the specimen appear light on a dark background is called a?
A darkfield microscope makes the specimen appear light on a dark background. It is an instrument used in light microscopy.
Why are specimen thin?
because the thinner it is the clearer it is too see inside
When should the high power objective be used?
When a very close view of the specimen is necessary. You can focus in on one part of the specimen.
Which rock specimen should lead the student to choice 4 path a?
gneiss is the answer
Does leaving a tourniquet on too long cause hemolysis?
yes! your specimen will be hemoconcentrated! if you have a long draw, just lift up on the tourniquet every now and then...the blood flow will be much better, and the specimen shouldn't get hemolysized!
What should you do if a specimen spills on your clothes?

Why is it important for a specimen viewed under the microscope to be thin?
A specimen being viewed under a microscope should be thin so that light can pass through the specimen. The thinner it is the brighter it will be. A thick specimen will block the light and all you'll get is a dark grey image. Also, more detail can be seen in a thin specimen because there will not be parts in front of each other, blocking the view.
What is dark field?
Dark field microscopy (dark ground microscopy) describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen (i.e. where there is no specimen to scatter the beam) is generally dark.

What is Dark field microscope?
A Dark Field microscope is one that has a special condensor (light source) that illuminates the specimen in such a way as to enhance the contrast even if it is unstained. When you look at a specimen in a dark field scope, it looks bright, but it is visible against a black background -- the 'dark field.'

A darkfield microscope makes the specimen appear light on a dark background. It is an instrument used in light microscopy.
What is a microscopic field?
A Dark Field microscope is one that has a special condensor (light source) that illuminates the specimen in such a way as to enhance the contrast even if it is unstained. When you look at a specimen in a dark field scope, it looks bright, but it is visible against a black background -- the 'dark field.'

What type of microscope makes the specimen appear light on a dark background?
dease nutts
If X-ray film is to dark what should you do?
If the film is too dark, the xray needs to be retaken with lower kV and mAS settings. Xrays that are only marginally too dark can be looked at under a bright light.
When should image threshold settings be changed?
When the images are too dark or light
Why do you cut a very thin slice of specimen to look under light microscope?
The light is reflected upwards, and passes through the specimen. It passes through easier (clearer) if the specimen is not too thick.
