- 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
- 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?
- Calculating Flow Rate: Pressure Source to Converging Nozzle
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 (this is like a fire hose system - slightly different for my actual application) The pressure of the pressure source is my independent variable, I am doing a sweep in excel
- Two Converging Lense Questions - Physics Forums
For a lens of focal length f, what value of the distance between the object and the lens[D0] would give an image with a magnification of one? Is it possible to obtain a non-inverted image with a converging spherical lens? Explain please? Any response would be greatly appreciated, and I
- 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 I have to now find focal length from the graph?
- Why is my COMSOL solution not converging? - Physics Forums
Hello, I'm a 2nd year student, and I'm trying to get to know COMSOL I'm starting off by solving simple problems with the incompressible Navier-Stokes model, but I keep having trouble with the convegence of the solution I keep getting the following error: "Failed to find a solution: The
- Is it possible to have a Mach number greater than 1 at the throat?
Now go back to a converging-diverging nozzle, consider the air gaining speed as the duct converges At some point, the Mach number reaches unity, at which point the only way to continue to accelerate through Mach 1 is by the duct now diverging
- Converging Lenses and image position - Physics Forums
Homework Statement Two converging lenses with focal lengths of 40 cm and 20 cm are 10 cm apart A 2 0-cm-tall object is 60 cm in front of the 40-cm-focal-length converging lens a Use ray tracing to find the position and height of the image do this accurately with a ruler Determine the
