    Undergrad Why does a spyglass or binoculars zoom in?

    And all the same about the star. I think it's interesting. A star that is billions of light years away emits rays of light. These rays diverge in all directions. How much of this light will reach the Earth? But even such a small Hubble telescope can give us a huge amount of information...

    Undergrad Why does a spyglass or binoculars zoom in?

    Ok. More or less I got it. But some questions remained. The lens is larger than the eye so it collects more light. But there are binoculars with lenses of different sizes but which give the same magnification. This leads to the second issue: the lens system. If it all comes down to lens size...

    Does it mean that just changing the angles at which light enters my eye I can change the object size and detail?

    Yes, I understand. but in the moon example, doesn't that mean I'll just see it bigger? How can I see it not only bigger but more detailed?

    Undergrad Why does a spyglass or binoculars zoom in?

    ok. Let’s take a light that came from a star. My eye just seeing a small dot in the sky but with binoculars or a telescope, I can see more information. But the beam of light that came from the star and hit the lens is very small. Where does information come from? Is it already there in the...

    Undergrad Why does a spyglass or binoculars zoom in?

    Why does a spyglass or binoculars zoom in? How does it work? I know a little about optics. But here's what interests me: how does a beam of light entering the binocular lens bring the object closer? This beam of light has certain information inside, and this information is "decoded" by...
