What is the purpose of examining your specimen slide using low power objective first nefore high power objective?
Step by step
Solved in 2 steps
- If you observe a specimen under this 20X objective and the specimen spans one-quarter of the field of view distance, how long is the specimen in micrometers?Describe the process to get a specimen into view using the 40X objective starting from the point after you have plugged in your scope and cleaned the objectives and slide.What is the objective lens used to locate the specimen and first focus? What is the difference in using a coarse adjustment knob and a fine adjustment knob?
- e) What is the total magnification of a specimen when viewed with the following objective: 400 Scanning High Power 400 Low power Oil ImmersionList the steps that you implement while using oil immersion to observe the specimen.What information can be obtained from the slides prepared by wet mount and hanging drop technique for microscopic observation? Give at least three (3) information. What are the limitations of each method. (Provide 2 limitations)
- What is the specific objective lens that is used to locate the specimen and first focus? Explain. What is the difference between using a coarse adjustment knob and a fine adjustment knob?When you are trying to find a specimen, you should use; The scanning objective The low/medium power objective The high power objectiveWhich of the following statements is/are TRUE? Kindly choose all that applies. Select the correct response(s): When FOV increases, the specimen magnification decreases. When FOV increases, the light intensity increases. When FOV increases, the specimen magnification increases. When FOV increases, the light intensity decreases.
- What are the differences between scanner, low power objective, high power objective and oil immersion objective? Introduce the terms stated above and explain comprehensively.You are asked to calibrate the ocular micrometer for the 4x objective using the stage micrometer. You observe 32 stage micrometer units line up with 15 ocular micrometer units. What is the value for each division of the ocular micrometer for this objective? (Round to the 1 decimal place)The field of view under the 4x objective is 3.3mm and a specimen looks like they can fit about 10 times across the field of view. What is the size of the specimen?
