Yeast cells are typically observed under 40x objective. the total magnification of the specimen is?
gregori [183]

The overall magnification of a microscope is calculated by multiplying the objective lens's magnification by the optical lens' magnification.

However, you must first ascertain the optical lens's magnification power before computing the total magnification.  The ocular lens typically magnifies 10 times.

Find out how much the objective lens can magnify. On the side of the lens is printed the magnification. The value may formerly be 4X, 10X, 40X, or 100X.

Multiplying the ocular lens' magnification power with the objective lens' power yields the compound light microscope's overall magnification. For instance, a 400X total magnification would be achieved with a 10X ocular and a 40X objective. The compound light microscope has a maximum total magnification of 1000X.
