## Schrodinger and De Broglie's Equation

$H_{\psi }=E_{\psi }$

1-D: $E_{TOTAL}\psi (x)=E_{k}\psi (x)+V(x)\psi(x)=-\frac{h^{2}}{8\pi ^{2}m}\frac{d^{2}\psi(x)}{dx^{2}}+V(x)\psi(x)$

### Schrodinger and De Broglie's Equation

In which situations would you use the Schrodinger equation and which one would you use De Broglie's equation?

Schrodinger's is used to calculate the energy level of atoms. De Broglie's is used to calculate the wavelength of a moving object.

### Re: Schrodinger and De Broglie's Equation

If you're dealing with quantum numbers and atomic orbitals in a question, you will most likely use Schrodinger's wave function equation. De Broglie's would be to find the wavelength (for instance, if you are given the mass and/or velocity of an object, then you would use De Broglie's equation).

I forgot to add that you can also use De Broglie's if you are given the wavelength and you need to find either mass or velocity (λ = h/mv).
