How Binoculars Work
Posted by delaney1019 | Filed under Uncategorized
Essentially, binoculars are just two telescopes mounted side by side, one for each eye. So to understand binoculars, you need to understand how a telescope works. Here’s an easy demonstration that you can try yourself. All you need are two ordinary magnifying glasses and a piece of tracing paper. Do this once, and you will understand forever how binoculars work. Hold the tracing paper on the opposite side of the magnifying glass from a bright object, such as a light bulb. Move the paper back and forth. At a certain distance, a small, upside-down-and-backwards image of the light bulb will form on the paper.
