- While looking into your compound light microscope you find that only part of the specimen is visible. What might be the cause? Question options: Insufficient illumination from the substage condenser. Iris diaphragm has not been properly adjusted. Your objective lens has not clicked fully into position. Your objective lens is dirty.During studying a thick heavily stained specimen under the microscope, it is better to light intensity adjustment has nothing to do with the clarity of the specimen. increase the light intensity passing through the specimen decrease light intensity passing through the specimen none of the options is correctThe ocular lenses magnify the specimen by how much? Question 4 options: 5% 10% 15% 20%
- 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:In this image a stage micrometer and an ocular micrometer are aligned so that the 10 o.u. line aligns with the 100um line. The 200um line of the stage micrometer overlaps with the 90 o.u. line of the ocular micrometer. What is the calibration for this lens? eyepiece graticule 40 50 60 70 s0 9 100 stage micrometer 0.8 um/ou O 8 um/ou O 1.25 um/ou 0.25 um/ouIf you have chosen the objective lens with 10x and the ocular lens magnification is also 10x. Then the total magnification will be 100x. True False
