What is the difference between a compound microscope and a stereo microscope?

• A compound microscope provides a 3D view of larger specimens at lower magnification, while a stereo microscope is used for viewing small specimens at high magnification.

• A compound microscope is used for viewing small specimens at high magnification, while a stereo microscope provides a 3D view of larger specimens at lower magnification.

• Both microscopes are used for viewing small specimens at high magnification.

• A stereo microscope is used for viewing specimens in complete darkness, while a compound microscope is used for viewing specimens in light.

What is the role of the diaphragm in a microscope?

• To magnify the specimen for better visibility.

• To control the amount of light that reaches the specimen.

• To focus the image of the specimen.

• To hold the slides in place.

Define total magnification in microscopy.

• Total magnification is calculated by adding the eyepiece magnification to the objective lens magnification.

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

• Total magnification is the maximum size an object can be viewed under a microscope.

• Total magnification is the distance between the eyepiece and the objective lens.

What is the function of the stage on a microscope?

• To hold the slide in place for viewing.

• To magnify the specimen.

• To illuminate the specimen.

• To adjust the focus of the microscope.

What is the difference between low power and high power objective lenses?

• Low power lenses have lower magnification (e.g., 4x) while high power lenses have higher magnification (e.g., 40x).

• Low power lenses are used for viewing larger specimens, while high power lenses are used for smaller specimens.

• Low power lenses are always colored, while high power lenses are always clear.

• Low power lenses can only be used in bright light, while high power lenses can be used in dim light.

What is the total magnification under medium power if the eyepiece is 4x and the medium power objective is 10x?

• 20x

• 30x

• 40x

• 50x

What is the typical range of magnification for a light microscope?

• 10x to 100x

• 40x to 1000x

• 100x to 2000x

• 1x to 10x

What is the purpose of the objective lens in a microscope?

• To illuminate the specimen.

• To focus light and magnify the specimen.

• To adjust the stage height.

• To provide color to the image.
