## Math Solution of Optical Instrument

When you use an optical instrument, it is something very simple like a magnifying glass, or more complex such as a telescope or a microscope, you’re usually trying to make things more so that you can more easily see the fine details. One thing to remember in this regard is that if you want to make bigger things, you always use mirrors or converging lenses. Mirror or diverging lenses always give smaller pictures.

When using a converging lens, it’s helpful to remember rules of thumb thesis. If the object is very far away, the picture will be tiny and very close to the focal point. As the object moves Towards the lens, the picture moves out from the focal point, growing as it Does so. The object and image are exactly the same size When the object is at 2F, twice the focal distance from the lens. Moving the object from 2F Towards F, the picture keeps moving out away from the lens, and growing, until, it goes to infinity When the object is at F, the focal point. Moving the object closer to the lens still, the picture comes in steadily Towards the lens from minus infinity, and gets smaller the closer the object is to the lens.
