Microscope lenses are those that allow an object to be magnified. These lenses are the eyepieces and the other is called objective. These lenses are called converging lenses and are on a common optical axis. The most commonly used objectives are 4, 10, 40 x and up to 100x. The eyepiece allows you to observe the image of the object selected by the lens, acting as a magnifying glass. It consists of two lenses: the lower or collector, and the upper, or eyepiece.
C is the correct answer I'm 100% sure. The other person who answered gave a well thought out explanation as to why.
multiplying the power of the objective lens times the power of the ocular lens.
multiplying the power of the objective lens times the power of the ocular lens
The power of the objective lens multiplied by the power of the ocular lens
i'm pretty sure it's spores
