But if u look at the complex solution of Schrodinger's equation, it also satisfies the general

equation of 1-D wave which is given by ---

(partial^2psi)/(partialx^2)=1/(v^2)(partial^2psi)/(partialt^2).

So, both the solutions

$\Psi(\mathbf{x},t) = Ae^{i(\mathbf{k}\cdot\mathbf{x}- \omega t)}$ (given by Schrodinger)

and

y=A Sin(kx-wt)

satisfy all the wave equation(1-D,2-D,3-D) . But Schrodinger is credited of finding the solution as complex phase factor. And this is also used as solution of matter wave.............Why ???

I have a doubt related to solution of Schrodinger's eqn.

Solution of Schrodinger's eqn. is given by -----

$\Psi(\mathbf{x},t) = Ae^{i(\mathbf{k}\cdot\mathbf{x}- \omega t)}$

But the general solution of wave eqn. is

y = A sin(kx-wt)

And this even satisfies the eqn....Then, what was the necessity of depicting the solution as complex phase factor.

Can anyone give me the derivation of mass change equation during relative motion

Recently some of my friends suggested that

M.L.Khanna would be the best mathematics book for Mathematics. I want your views on that.........................

Prove that

(tan4A + tan2A)(1 - 3a * A) = 2 * tan3A * A

The sixth term of an arithmetic progression is 3 and the common difference exceeds 0.5. At what value of the difference of the progression is the product of the first, the fourth and the fifth term is the greatest.. Give full explanation

The first term of an arithmetic progression is equal to unity . At what value of the common difference is

a₁a₃+a₂a₃ at a minimum . Give the full explanation.

$\Psi(\mathbf{x},t) = Ae^{i(\mathbf{k}\cdot\mathbf{x}- \omega t)}$

and

$\frac{\partial}{\partial t} \Psi = -i\omega \Psi$

Can please anyone tell how these two formulas arise ? from schrodinger's wave eq

$\Psi(\mathbf{x},t) = Ae^{i(\mathbf{k}\cdot\mathbf{x}- \omega t)}$

and

$\frac{\partial}{\partial t} \Psi = -i\omega \Psi$

Can please anyone tell how these two formulas arise ? from schrodinger's wave eq.

Can anyone tell how this happens

Expressing the wave function as a complex plane wave

and

(By Schrodinger)

Right ! But I want to know it's relation with electric and magnetic field enerrgy.

Is it correct to say that

Energy of light = electric field energy + magnetic field energy.

If not then what is the relation between energy of light and electromagnetic field energy

Plz help ....................

Thanx a lot madmax !!!!!!!!!!!!!!!!!!!

The equivalence of mass and energy expressed by the relation E = mc² is a fairly direct consequence of Maxwell’s conception of electromagnetic waves. According to Maxwell’s equations, the energy density of electric and magnetic fields e and b is (e² + b²)/(8p) and the momentum density is (e x b)/(4pc). Thus in the case of radiation (when e and b are equal and orthogonal) the energy density is E = e²/(4p) and the momentum density is p = e²/(4pc), so we have the important relation p = E/c. In addition, the energy of a pulse of light for relatively moving systems of reference transforms in proportion to its frequency, consistent with Planck’s relation E = hn. Given these facts, we can show that light pulses of total energy E reflecting inside a closed container contribute E/c² to the inertial mass (i.e., the resistance to acceleration) of the container.

this one I got from a site.

Here it states that, electric field=magnetic field(for light)

But in the ncert physics of class 12 and many other sites it is given that

E/c=B

E=electric field

B=Magnetic field

c=speed of light

So, which is correct

What is the relation between electric field and magnetic field in an electromagnetic field ?

plz. help !!!!!!!!!!!!!!!!!!!!!!

Einstein derived the mass-energy equivalence from transverse Doppler Effect

Can anyone tell that how was transverse Doppler Effect derived ???????????
