Homework Statement An object is locted 15cm infront of a convae lends with a focal length of 10cm. use ray tracing to determine the location of the image. try to draw to scale i)is the image upright or inverted? ii)is the image real or virtual? iii)use your ray-tracing diagram to...

If I have an object and in front of it there's a diverging lens, and in front of that (furthest from the object) there's a converging lens can I just ignore the diverging lens when ray tracing for the image formed by the converging lens? I figure if I were able to draw an infinite number of...

Just a check here... I'm doing some ray diagram practice for optics and I've hit a road block. Hyperphysics is stating that for a concave mirror o is usually negative due to it measured against the direction of light propagation when applied to the mirror equation (below)...

How is it possible to see the light path of a green laser pointer?

Homework Statement Sketch the indicated traces, and the graph z = f(x,y) f(x,y) = x - 2y z = 0; z = 1; x = 0; y = 0The Attempt at a Solution z = f(x,y) = 0 = x - 2y -> y = -x/2 the trace is a line z = f(x,y) = 1 = x - 2y -> y = x-1/2 another line going through x = 1/2 z =...

Im having a discussion with someone about sanctions leading up to the war in Iraq. I was wondering if anyone could give me a source which shows where the money went in that program (corruption), and what country the Iraqi oil went to.

I know that intersection tests can typically (for hit detection in games) be computed in log n time with reasonable accuracy, but there is a problem that I see with using hierarchical bounding volumes in ray tracing. For example, a ray may intersect a bounding volume however due to the shape...

Can anyone brief of on the different rules for doing ray tracing for both concave and convex lenses, as well as both concave and convex mirrors?? I understand the concepts but i can't seem to keep ray tracing in my head from the way our textbook explains it...

Homework Statement I have a concave lens where f < do < R. I have to provide a ray tracing diagram. The Attempt at a Solution I drew the focal ray through the focus and parallel to the principal axis. I drew the principal ray parallel to the principal axis then through the focus. I...

Homework Statement If the focal length of the concave lens is -7.50 cm, at what distance d_o from the lens should an object be placed so that its image is formed 3.70 cm from the lens? What is the magnification m produced by the concave lens described in above? Where should the object be...

Hello all, I have a small problem with COMSOL. I am trying to use the particle tracing feature, more precisely I want to use the boundary coordinates to specify where are the points from which to trace the electrons. From what I understand in the User's Giude, the Boundary Coordinates feature...

If i found a computer on the street and it had no information on the owner or previous user, is it possible to to then find and locate where it had been used and thus a possible owner?

Hey, new to the forum. I'm currently taking my first programming course, and in one of the assignments, I was asked to trace the following Fortran77 program fragment by hand and determine the final values for n and m: integer n, m, k, j n = 0 m = 0 do k = 1, 3 do j = k, 1, -1...

Homework Statement An object is 6.0 cm in front of a converging lens with a focal length of 10 cm. Use ray tracing to determine the location of the image. Is the image upright or inverted? Is it real or virtual? The Attempt at a Solution According to my ray tracing...there is no...

Hi all, I'm confused about the concept of wavefronts in ray tracing .. each ray is considered a wavefront? or what exactly is a wavefront in ray tracing? In the reception sphere, it is mentioned that only one ray should be received from an actual path. I don't get it .. does this mean that...

does every second repeat itself when time moves forward,but the events that occur in each second are not the same,so do we know the no.of seconds that have passed from the time life began?

Hi All, I am a beginner at Electromagnetics I'm implementing ray tracing SBR to predict propagation of waves. Each ray contribution will be in the form of: Ei = (some factors) e ^ (- j k r) u(theta, phi) where k = 2 pi / wavelength, r is the total unfolded path I'm not sure about...

Hi there! Up to now, I've been not so familiar with theoretical condensed matter physics but now I have to calculate a partition function of the type Z = \mathrm{Tr}\,\mathrm{e}^{-\beta(a^\dagger a + a^\dagger b + ab^\dagger)} where a, a^\dagger, b, b^\dagger are fermionic...

Is anyone familiar with the "y n u" ray trace method for optical systems, using paraxial rays where Snell's law is approximated using: n1sinx1 ≈ n1tanx1 ≈ n1u1 = n2u2 If anyone is familiar with this, I'd be interested to discuss the finer points of "a-ray" and "b-ray" tracing, as well...

i tried to trace this recurtion for small numbers but i don't know how to write down in an organized way int a(int n,int count){ int i; for(i=0;i<n;i++) count =a(i,count); return count+1; } a(0,0) is easy its 1 a(1,0) a little harder it returns 2 but when i get...

The motion diagram below shows the position of a seat on a Ferris wheel at 12 moments. One full rotation is shown; the positions at moments 0 and 6 are labelled. For each of the following questions, choose the appropriate direction from the second diagram...

Ray Tracing...HELP! Homework Statement An object is 6.3 cm from a convex mirror with a focal length of 10 cm. Use ray tracing to determine the location of its image. Homework Equations The Attempt at a Solution 1/f = 1/s + 1/s' 1/f - 1/s = 1/s' 1/10 - 1/6.3 = -0.0587 cm ^ -1 =...

Ok, so this is probably a really basic question, and I've got a feeling that my brain is just too 'fuzzy' just now and that all my problem is is simple arithmetic, but here it goes... 1. Determine whether or not the box with vertices at (2,1), (5,1), (5,5), and (2,5) is intersected by the...

After ingestion of glucose, trace the path of the hydrogen atoms in glucose beginning within the digestive tract and ending with the oxidation of the glucose during aerobic respiration. Can anyone help me out with this problem? Thanks to everyone in advance!

Homework Statement 1) In a sequential process, U(235,92) plus a neutron forms the compound nucleus [U(236,92)]* which then fissions; the fissions then produces decays. If the initial fission fragments are Ba(143,56) and Kr(90,36), illustrate a process leading to the final stable nuclei...

Where can all the classic papers by the experimentalists that layed the foundation for nuclear physics be found?:confused: Rutherford, joliot-curie, fermi, lawrence, Hahn ect. Im very interested in reading exactly how they setup there experiments, the conclusions they drew and so on.

Dear all, The possibility of black holes can be traced back to a special solution of the Einstein's equations, the famous Schwarzschild metric in 1916. I find this very impressive, since at that time, the GR was a very young theory and it would have been more than natural to be skeptic...

how do you trace an ip address? I'm not looking for anyone's exact location.. just mainly city/state/country and how accurate can it be

I recently received a threatening message in my yahoo messenger from someone I do not know... is it possible for someone to be able to trace my telephone no. and address etc. this way? They say they have... if so, can theirs be traced from my end as well to find out who this is? shaken

Here is the problem: A glass sphere with a diameter of 5cm has a scratch on its surface. When the scratch is viewed through the glass from a position directly opposite, where is the virtual image of the scratch, and its magnification? The glass has an index of refraction n=1.50. Explain the...
