What happened to the orientation of the letter? Draw the letter “e” look under the 4X objective. 2.
When you move the slide to you right, in which direction does the image move. 3.
What happened to the size of the field as you switched from the 4X to the 10X to the 40X objectives? 4.
What happened to the brightness of the object as you switched from the 4X to the 10X to the 40X objectives? a.
As we increased the magnification power of the microscope, the brightness diminished. 5.
When comparing high power to low power which one has the largest diameter field of vision? a.
Which power (low or high) will allow you to see more of the object? a.
Which power low or high will magnify the object more?
When switching from low to high power, the area in the field of vision becomes smaller and darker thus preventing you from seeing the organism. A solution to this problem would be to center the specimen prior to switching from low power to high power. 9.
Both compound and dissecting microscopes use a magnifying tube over the sample and a light source under the sample that allow you to see the object closely and clearly. The magnifying tube on both can be rotated to increase the magnifying power (giving a closer view). Both types are relatively similar in size and can be picked up, moved and set on different flat surfaces easily. Compound and dissecting microscopes have many similar parts, including a lens, stage, focus knob and coaxial controls that allow you to adjust the distance between the lens and the stage. 10.

Suppose you measure a scanning (4X) field of vision diameter with a stage micrometer and it is 2mm. If high power is 40X and gives 10X more magnification than scanning power, how big will the diameter of the field of vision be using high power? a.
