The question is find R Thevenien using Voltage test source across terminals a and b of the following circuit: http://img255.imageshack.us/img255/8660/rthevenen.png I did it by adding a 20 test voltage source and used mesh to get the following 4 equations of the 4 meshes ( I deactivated...

Well, yes you are right. Now, I do understand how to find number of images but still I don't get the line tracing thing. I contacted Dr Walter H.G. Lewin, Physics MIT lecturer, but unfortunately he replied that my question requires more than 10 minutes of his time and that's why he can't...

Actually, no, that applet is not correct, based [1], number of images produced by hinged mirrors at an angle "x" can be found using: 1. If 180°/q = x, an integer then the number of image formed, N = 2x-1, regardless of where the object is. 2. If 180°/q = x + 0.5, number of images formed ...

Still. the correct answer is 5 but I don't know the reason

one mirror = one image

Any solution?

Homework Statement In the following diagram, why not 6 images are produced? Explain thoroughly. And mention the amount of images produced. Problem Image: http://img691.imageshack.us/img691/8315/imageproduced.jpg or http://file15.9q9q.net/preview/92743229/Image-Produced.jpg.htmlPlease...
