Web27. okt 2024 · Like focal length, focal ratio can tell you a lot about a telescope: larger f/numbers imply higher magnification with a given eyepiece and a narrower field of view, smaller f/numbers the opposite. Additionally, an f/number can be described as ‘fast’ or ‘slow’, and this reveals how a telescope will perform when used for astrophotography. WebSo you would need a strong source of white light (or light that is composed of a broad range of visible light frequencies). The sun will do for most purposes. Then you need an object that is capable of dispersing a ray of light. This can be a) an 3D object (prism) with a refractive index greater than air or b) a diffraction grating. manhattan beach luggage storage for one day
