      Hello 🙂 I had to do some googling to answer this one but from what I can tell usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4x, 10x, 40x and 100x powers, this is sort of like how much you zoomed in you can get using that particular microscope. Why these particular lenses I don’t know, I imagine they are at pretty useful magnifications for most basic microscope work! I tend to use 4x or 10x when I look at my fungal hyphae!
