• Compound Light Microscope

• Dissecting Microscope

• Both

• Neither

A dissecting microscope has __________ objective lens/lenses and goes up to __________ magnification.

• three; 40X

• one; 40X

• three; 100X

• one; 100X

What part of the microscope focuses and controls the size of light?

• Rheostat

• Condenser and Iris Diaphragm

Magnification is:

• The process of reducing the size of an object

• The amount that an image has been enlarged

• the technique of changing the color of an object
• the method of measuring the distance to an object

Resolving power is:

• the maximum distance an object can be seen
• how distinguished a sample is from its background

• the extent to which object detail is preserved during magnification

• the speed at which light travels through a medium

I am viewing a tissue slide on a compound light microscope through a 40X objective lens. What is the total magnification?

• 100X
• 200X
• 800X
• 400X

• Depth of field decreases as magnification increases.
• Depth of field increases as magnification decreases.
• Depth of field decreases as magnification decreases.
• Depth of field remains constant as magnification increases.
