Exploring Biology in the Laboratory

With which objective do you use the course focus knob?

Lower power 4X

How should you properly cary the microscope?

With both hands

What happens to the field of view as you decrease the magnification?

It becomes larger and less defined (focused)

Define the term resolving power.

The amount of resolution in the image. How clear it is.

What is the total magnification of the micriscope with an occular power of 10 and an objective power of 4X?

10x4X=400

Why is it easier to focus using the lower powered objectives than the higher powered objectives?

Because the Depth of Field view is larger and the objectives do not need to be as close to the slide.
