What is the total magnification if you are using an objective that is 40x?
 A 4x B 40x C 400x D 4000x
Explanation:

Detailed explanation-1: -Total Magnification: 40-400X. 10X Eyepiece.

Detailed explanation-2: -The total magnification of a high-power objective lens combined with a 10x eyepiece is equal to 400x magnification, giving you a very detailed picture of the specimen in your slide.

Detailed explanation-3: -To get the total magnification level you must multiply the magnification of the ocular lens by the magnification of the objective lens. So, if you are viewing your slide under the 40x objective lens you would multiply that by the 10x of the ocular lens for a total magnification of 400x.

Detailed explanation-4: -If the 40X objective was being used, the total magnification would be 400X. (10 x 40 = 400). multiplying the magnification of the ocular lens by that of the objective lens. At higher magnification the light intensity should be decreased so that the image will have good contrast.

Detailed explanation-5: -The compound microscope typically has three or four magnifications-40x, 100x, 400x, and sometimes 1000x. At 40x magnification you will be able to see 5mm. At 100x magnification you will be able to see 2mm. At 400x magnification you will be able to see 0.45mm, or 450 microns.
