describe two ways you can adjust the light intensity on your compound microscope.
Homework Answers
Two ways of adjusting the light intensity on Compound microscope are:
- 1. By adjusting Rheostat
- 2. By adjusting Iris diaphragm
Explanation:
The contrast of the image can be enhanced by controlling the light intensity in the compound microscope which can be accomplished by using:
1. Rheostat: Rheostat is a light intensity control knob. It can reduce or increase the current to the light source (lamp) and hence help in controlling the light intensity by dimming or brightening the lamp.
2. Iris diaphragm: Iris diaphragm can be widened to allow more light to pass through and can be narrowed to allow less light. When the diameter is reduced, diaphragm is encircled to a pin hole that prevent stray light rays. Hence, adjusting the diameter of iris diaphragm controls the amount of light intensity

Which of the following demonstrates the proper use of the compound light microscope? A. When using the oil immersion lens, we can also use the coarse adjustment knob to focus to get a clearer image. B. We should adjust the iris diaphragm to allow more light in at higher magnifications. C. If we are not able to get a clear image with the oil immersion lens, we should bring the high dry(40x) into position to refocus. D. When viewing a...

RESOLUTION: This property of the compound microscope is the degree to which the detail in the specimen is retained in the magnified image. It is the ability of a microscope to distinguish two closely spaced objects as separate and distinct entities. Conventional light microscopes have a resolution of about 0.2 μm. RESOLVING POWER (d) is the closest spacing between two points at which the points can still be seen rly as separate entities. The smaller the resolving power, the smaller...
