Unformatted text preview: 1 2 ; 1 2 t must be a whole multiple of 2 for the coecients to return to their original values. Answer: The coecients are c n (0) e i (2 n +1) 2 t Now if t is 2 , the argument of the exponential equals i times an odd multiple of . That makes the exponential equal to minus one. It takes until t = 4 until the exponential returns to its original value one. 7.1.2.3 Solution schrodsolc Question: Write the full wave function for a onedimensional harmonic oscillator. Formulae are in chapter 3.6.2. Answer: Using the give formulae ( x, t ) = s n =0 c n (0) e i (2 n +1) 2 t h n ( x ) 7.1.3 Energy conservation...
