Activity 1:

Why do you have to adjust the light as your magnification increases?

What is happening to the size of the field of view as the magnification increases?

What is happening to the amount of light that is getting into the lens as the magnification increases?

What are two ways you can change the amount of light?

Under the 4X scanning lens, are all 3 threads simultaneously in focus? _____________________

Under the 10X low power lens, are all 3 threads simultaneously in focus? __________________

Insert your screenshot of the “Test your knowledge” section.

Expert Solution

As the magnification increses amount of light entering the lens decreses hence we need to adjudt the light intensity.

As the magnification increses, the field of view decreases.

Amount of light decreases as magnification increases.

Amount of light can be changed by either using light adjusting knob which controls the intesity of light emitted by light source in microscope or it can also be controlled by slits below the stage which will block some portion of light falling on sample.

Lower the magnification, the threds may appear simultaneously if they fall under the same field of view. As the magnification increases all point may not be visible or distinguishable under same focus.
