  • What do convergence and divergence mean? And why do they matter?
    I understand that when a series diverges, y doesn't approach 0 when x approaches infinity, and converging series do But what does this say? I just want to understand some applications NOTE: I'm still on integration by parts, so try to explain in simple terms This site scares me sometimes xD Thanks!
  • Calculating Flow Rate: Pressure Source to Converging Nozzle
    Then there is a converging nozzle, which I have calculated the resistance coefficient using Crane's Manual and it has an outlet to the atmosphere I have tried to simplify the system The full system is a pressure source, converging nozzle which has outlet into original diameter at converging nozzle inlet followed by hose to outlet to atmosphere
  • Reason for Different Focus Distances in Converging Lens Lab
    we used a converging lens and a screen with white paper in front of a window to form an image of a distant tree outside This was about 15cm When we used an optics bench and a candle to figure out the focus, it was 16 3cm What would be a reason for the difference in the number?
  • Identifying Converging and Diverging Lenses . . . - Physics Forums
    Draw the three rays designated in your text, a ray that passes through the first focal point and then becomes parallel to the principle axis after refraction, a ray that simply passes through the center of the lens and does not refract, and a ray which is parallel initially then passes through the second focal point after refraction
  • Two Converging Lense Questions - Physics Forums
    Yes, it is possible to obtain a non-inverted image with a converging lens As long as the object is between the focal length point and the lens it is possible Of course this would be a virtual image and the image would be magnified m=-d(image) d(object) If m=1 than we have an equation where we can put d (object) = - d (image)
  • Graphically determining the focal length of a converging lens
    Homework Statement: Graphically determining the focal length of a converging lens by graphing the given object distances (do) and image distances (di) Relevant Equations: 1 f = 1 do + 1 di So I have plotted all the given data points on a graph, putting 1 di on the y- axis and 1 do on the x-axis
  • Find the distance between and object and its image - Physics Forums
    Homework Statement How far apart are an object and an image formed by a 72 4 cm focal length converging lens if the image is 2 54x larger than the Insights Blog -- Browse All Articles -- Physics Articles Physics Tutorials Physics Guides Physics FAQ Math Articles Math Tutorials Math Guides Math FAQ Education Articles Education Guides Bio Chem
  • Converging Vs diverging sequences - Physics Forums
    A sequence is made up of two sequences an=(n^2) (n+2) - (n^2) (n+3) The problem asks for the solver to work out if it's converging or diverging, and find a limit if possible My first thought was to write both over a common denominator and then divide through by the dominant term; this
  • Rational sequence converging to irrational - Physics Forums
    In the textbook I have (its a textbook for calculus from my undergrad studies, written by Greek authors) some times it uses the lemma that "for any irrational number there exists a sequence of rational numbers that converges to it", and it doesn't have a proof for it, just saying that it is a
  • general topology - Compactness implies that every net has a converging . . .
    Onwards let subnet have its classical definition Clearly in any topological space $(P)$ implies that every net has a converging subnet So the comment implies that there are spaces that are compact but still not satisfy $(P)$ What would one such space look like?
