Step by step
Solved in 3 steps
- A michroscope has a 20x ocular and two objectives of 10x and 43x respectively: calculate the apparent magnification for low and high power lenses.After focusing the specimen in hpo, you switched the objectives halfway and dropped enough immersion oil before clicking the oio lens into place. but when you viewed the specimen, you found the image to be blurred. what should you do:f I use the 10x eyepiece and the 40x objective, what is the magnification? Select one: 4 diameters 40 diameters 4000 diameters 400 diameters
- Match the lens (condenser, high-dry, low-power, ocular, or oil immersion) to itsdescription. Choices may be used more than once. This objective lens provides the lowest magnification.When using the 10x lens to view a specimen, what is the total magnification of the specimen to the eye? A. 10x B. 100x C. 400x D. 1000xMatch the lens (condenser, high-dry, low-power, ocular, or oil immersion) to itsdescription. Choices may be used more than once. This lens collects and focuses light from the lamp onto the specimen on the slide.
- A student is viewing the letter "e" on a slide. The studentcan clearly see the letter when using the 4X and 10X objectives, but when the 40X objective was used, the "e" was no longer visible. What happened?If the ocular lens is 10x, what would be the total magnification for the following objectives lenses? 5x 17x 35xThe primary difference between a TEM and SEM is in a. magnification capability b. colored versus black-and-white images c. preparation of the specimen d. type of lenses
