I'm confused about choosing the value for energy in quantum mechanics problems such as in scattering, tunneling, boundstates.. problems because this affects later calculations. Given the potential in some regions, how do I decide energy to be negative or positive, or greater/less than the energy...
Yeah, i think so. But at first, i thought if there is a positive particle between the plates then there will be two forces acting on the particle. Add them up and divide it by the charge then we will get the field strength ??
Homework Statement
Two plates each have an area of 80cm2 and are placed facing one another in a vacuum. If the top plate carries a positive charge of 25nC and the bottom plate carrie, a charge of -25nC. Find the electric field strength between them.
Permitivity of free space = 8.9 * 10^-12...
Thank you very much.
Actually, the problem i have to solve is to determine number of light regions if i use two monochromatic lights in the double-slit experiment
What will we see on the screen in double-slit experiment if I use two radiation have wavelength l_1 and l_2 . I know there will be two systems of interference fringe, call I and II. But what if one light region of I is coincident one dark region of II ?
And then how many light regions do we...
