Question
The Microscope 3. Each of the following statements is either true or false. If true, write T on the answer blank. if false, correct the statement by witing on the blank the proper word or phrase to replace the one that is underlined 1. The microscope lens may be cleaned with any soft tissue 2. The microscope should be stored with the oail immersion lens in position over the stage 3. When beginning to focus, use the scanning objective lens 4 When focusing on high power, always use the coarse adjustment knob to focus . A coverslip should always be used ith wet mounts 4. Match the microscope structures in column 8 with the statements in column A that identify or describe them. Column A Column B 1. platform on which the slide rests for viewing 2 used to adjust the amount of light passing through 3 controls the movement of the slide on the stage 4 delivers a concentrated beam of light to the specimen 5 used for precise focusing once initial focusing has a. coarse adjustment knob b. condenser c fine adjustment knob d. iris diaphragm lever e. mechanical stage f. nosepiece g. objective lenses h. ocular lens i stage the specimen been done 6. carries the objective lenses; rotates so that the differ- ent objective lenses can be brought into position over the specimena. 5. Define the following terms total magnification Viewing Objects Through the Microscope 6. Complete, or respond to, the following statements 1. The distance from the bottom of the objective lens to the surface of the slide is called the Assume there is an object on the left side of the field that you want to bring to the center (that is, toward the apparent right) Iin what direction would you move your slide? The area of the slide seen when looking through the microscope is the 2. -3. 4. ifa microscope has a 10x ocular lens and the total magnification is 950x, the objective lens in use at that time is . 42
Explanation / Answer
Answer 3.
1. False
It requires special microscopic tissue.
2. False
With scanning lens.

Answer 5. Magnification refers how many times an image in the microscope has been zoomed so that we can view it clearly.
For Eg, if the eyepiece is 15x and among objective lenses scanning lens is used having power of 10X. Then, magnification becomes 15 X 10= 150X
Resolution refers to the shortest distance between 2 points on a specimen that can be resolved by an observer as 2 separate entities. The compound microscope can resolve the 2 points if they are more than 200 nanometers apart.
Answer 6.
1. Working distance
2. Right side
3. Field area
4.95X, because magnification is eyepiece X objective lens
