What is the function of the light source in a microscope?

Back

The light source illuminates the specimen, allowing it to be seen more clearly under the microscope.

Front

What is total magnification in microscopy?

Back

Total magnification is calculated by multiplying the magnification of the eyepiece by the magnification of the objective lens.

Front

What is the purpose of the coarse adjustment knob?

Back

The coarse adjustment knob is used to quickly bring the specimen into focus by moving the stage up or down.

Front

What is the purpose of the fine adjustment knob?

Back

The fine adjustment knob is used for precise focusing of the specimen after using the coarse adjustment knob.

Front

What does the diaphragm do in a microscope?

Back

The diaphragm controls the amount of light that reaches the specimen, enhancing contrast and detail.

Front

What is the total magnification at low power (using the 4x objective)?

Back

The total magnification at low power is 40x (4x objective x 10x eyepiece).

Front

What is the total magnification at medium power (using the 10x objective)?

Back

The total magnification at medium power is 100x (10x objective x 10x eyepiece).

Front

What is the total magnification at high power (using the 40x objective)?

Back

The total magnification at high power is 400x (40x objective x 10x eyepiece).

Front

What is the function of the stage in a microscope?

Back

The stage holds the slide in place and allows for movement to view different parts of the specimen.

Front

What is the base of a microscope?

Back

The base is the bottom part of the microscope that supports the entire structure and keeps it stable.
