Microscopy Flashcards
The amount of light entering a microscope may be adjusted by regulating the
Diaphragm
If the ocular on a microscope is marked 10x and the low-power objective is marked 15x, the total magnification is
150x
The size of the light beam that passes through the microscope is regulated by the
Condenser
Changing objectives by revolving the nosepiece will still keep the specimen in focus
Parfocal
Which of these is not true when changing magnification from low power to high power?
Illumination should be decreased
The ability of a microscope to distinguish between two points as separate objects is called
Resolution
The advantage of using immersion oil is that it has special_____ properties that permit the use of powerful objective in a narrow field of vision.
Light-transmitting
The uniform circle of light that appears when one looks into the ocular is called the
Microscopic field
In determining the position (depth) of the colored threads, ____(red,green/blue,yellow) colored thread was in the middle.
Red
If you move your slide to the right, the specimen moves to the _____ as you are viewing it microscopically.
Left
After switching from low power to high power, _____ (more or less) of the specimen will be visible.
Less
Microscopic field size____ (increases or decreases) with higher magnifications.
Decreases
The distance between the objectives and the slide is called the
Working distance
A photograph of a specimen taken through a compound light microscope is called
Photomicrograph
An ocular of 10x used with an objective of 40x gives a total magnification of
400x
