Please anyone? The report is due in at 3.30 today and I would really like to have the analysis of the derivation included in it. Its not essential but it would essentially round the whole thing off nicely. Thanks

Well ideally the simplest way possible. Or even just an explanation of the steps. I am so glad that I don't have to understand it at this point. :smile:

I am looking for the simplest possible derivation of the diode equation. I need it to reference to it in my advanced higher project. Basically I have to dissect it. I unfortunately don't know how to derive it and I can't find one simple enough to use. This is what I am trying to end up with...

The problem here is that by measuring the photons momentum, you then in fact change it.

Your working seems correct to me...

Thats what I get when I shove the last line into some software. So I am guessing that you have went wrong somewhere... Unfotunately its too late at night for me to think clearly. This is just a heads up.

It would eventually corrode. But the way it works is that zinc is an electron donor. When the copper is ready to corrode, or oxidise (lost an electron), the zinc is there waiting to give it another to replace the lost electron. Obviously this cannot go on indefinately. Its the same reason why we...

If a reaction is endothermic then it takes in heat. Which means that if we raise the temperature of the reaction we give it more heat to take in. Which in turn means that the reaction can form more products. The equilibrium changes. The same thing happens to an exothermic reaction if we lower...

If we take a photon and split it so that the two are entangled, then no matter what we do to one happens to the other INSTANTLY. So you may think: "Hey I can send messages faster than light using this method." But you can't. Think back to the whole wave particle duality thing. Its a wave...

Thats not entirely true. If we take a radio signal broadcast at 100 MHz then it would have a wavelength of 3m. Yet there are those very tiny radio's only a few centimeters long which manage to pick up the signal quite clearly? These are only around 1/1000 the length of the wavelength. I would...

We would never be able to "see" a photon as the act of seeing things is our brain interpreting certain physical properties of photons in a certain way. These photons have bounced off of something which is what changes the properties. (wavelength in this case giving colour). We can only see...

Sorry that was me misreading the post. Another problem is still there. Even though we have two equations we have three variables. (I missed out lambda last time). You would need 3 equations for this to work.

To me it is just a way of finding a ratio between two numbers. I know it is not the most accurate definition but it works in my mind.

There are 4 unknowns in this. A, B, Gamma, Theta. There may be a way of solving this but not with any form of simulataneous equations of matrices i wouldn't think. Don't hold me to that though.

The third layer is identical to the first layer. And the fourth would be identical to the second and so on. It is basically the way in which the atoms stack together the best. If all the layers were identical there would be too much empty space between atoms.
