1. The problem statement, all variables and given/known data A particle of mass m moves in one dimension in the following potential well: V(x)=infinity, x<0 , x>L/3 V(x)=0 , 0<x<L/3 a)Circle the general functional form of the 1st excited wave function phi_1(x) in the region 0<x<L/3. k is a positive constant; A is constant as well; i) A sin(kx) ii) A cos(kx) iii) A exp(kx) iv) A exp(-kx) b) use the boundaries conditions to determine k c)Find A d)Find the 2nd excited state) 2. Relevant equations 3. The attempt at a solution a) I figured out was iv) b) Not sure what to do here but I will give it a try; A*exp(-k*L/3)-A*exp(-k*0)=0 and A*exp(k*infinty)-A*exp(-k*infinity)=infinity) c) I would squared phi to get A; (A*exp(-kx))^2=0, x=0...L/3 d) E=n*h*omega, where n=2?
