1. The problem statement, all variables and given/known data
Q.1Why when the particle's kinetic energy is smaller, the wave has longer wavelength and higher amplitude???
Q.2 Why the length of box decrease in ground state???

<All in attachment>

2. Relevant equations



3. The attempt at a solution
Q.1 wavenumber k= \frac{\sqrt{2m(U-E)}}{\hbar} , isn't it?
so KE decreases, wavenumber decreases, wavelength increases????
But isn't the amplitude just (2/L)^(1/2), from the normalization techinque???

Q.2 I really do not know why the box suddenly "contract" in the ground state.

can someone tell me why the amplitude of wave is affected by kinetic energy(E-U)?
