after doing a little research, I come to realize that the diffusion equation (Fick's first law) is actually
Flux = -D[(\DeltaC)/(\Deltax]
where D is the diffusion coefficient;
where C is the concentration
where \Deltax is the thickness of the membrane
therefore, -3x10^-5...
Homework Statement
Calculate the flux of oxygen across a square centimeter membrane [2\mu, or 2x10 ^{-6}m thick if the concentration on the right hand side of the membrane is 4mL/L and on the left side is 2mL/L.

Flux = dC/dx = D[C2-C1] where...
Homework Statement
The resolving power of a microscope depends on the wavelength used. If one wishes to "see" an atom, a resolution of approximately 1.00 x 10^-11m would be required.
a) If electrons are used (in an electron microscope), what minimum kinetic energy is required for the...
Yea sorry about that.
When light moves from a medium of air to a higher medium, say glass, the angle of light will diffract inward, making the image appear closer than it actually is. But in this case we have an n1 (air), n2 (convex/ concave glass) then a medium of water (n3)
Would the light...
So is white light defined as "light from a single wavelength?" If this is so, there will be no interference and light through the slits would never interfere, right?
Diffraction by definition is the divergence of light from its initial line of travel.
But images can't diffract through walls, right? Diffraction depends on coherent sources of light waves from a monochromatic source. wrt the double slit ex. right?
Homework Statement
Youngs double-slit experiment is performed with 589nm light and a distance of 2.00m between the slits and the screen. The tenth interference minimum is observed 7.26mm from the central maximum. Determine the spacing on the slits.Homework Equations
Iavg = (Imax) cos^2 [(pi d...
Homework Statement
how come we can hear around corners but we can't see around corners?
Homework Equations
The Attempt at a Solution
because the wall is obstructing the image?
Homework Statement
Suppose a reflected white light is used to observe a thin transparent coating on glass as the coating material is gradually deposited by evaporation in a vacuum, Describe color changes that might occur during the process of building up the thickness of the coating...
Homework Statement
How would white light in the double slit experiment be different from the pattern of a normal monochromatic diffraction?
Homework Equations
The Attempt at a Solution
No idea
Homework Statement
Why do fish appear bigger when you look at them through a fishbowl?
Homework Equations
The Attempt at a Solution
because objects in water appear bigger than they actually are? this has to do with change in the medium from air n1 to water n2?
Saketh, I thought that you had to know te direction of the current before you can apply the right hand rule?
OK, i think I got this one. (thanks for the hint btw!) When the right hand rule is applied to each of the 4 sides, the Fb of each side will cancel itself out and there will be no net...
