Determining the Focal Length of a Concave Mirror JSUNIL
Algebra: Parabolas. I have a math problem that requires me to find the focal length of a parabola using the information given on a graph. It is a standard horizontal parabola, the formula being y^2 = ax.... Just add a little maths! This process also enables you to get to know your telescope more. Factors you need to know: Focal length(mm) or focal ratio; Size of eyepiece (mm) Magnification = Focal length (mm)/size of the eyepiece(mm) If the Focal length was not provided and you only know the focal ratio. Focal length=F-ratio x aperture of your telescope Example 1: Saxon 1309EQ2 Reflector

F here is the lens’ focal length in centimeters. In cases like this the angular magnification is independent from the distances kept between the magnifying glass and the eye. When holding the lens very close to the eye, the object is positioned nearer the lens, larger angular magnification can be obtained with this formula:...
the magnification is the focal length of the objective divided by the focal length of the eyepiece... so -- don't I need to tell you the focal length of the objective? Ah, but I have. Since the f-ratio is the focal length of the objective divided by the diameter of the objective, f
