What Are the Correct Statements About a Quantum Harmonic Oscillator?

Click For Summary
SUMMARY

The correct statements about a 1D quantum harmonic oscillator include that the discrete energy states are given by (n + 0.5)hw, confirming option (b), and that the lowest energy state wave function is represented as ~exp(-α²x²/2), confirming option (c). Additionally, the probability of finding the particle outside the classical limit is indeed non-zero, validating option (d). Therefore, options (b), (c), and (d) are all correct based on quantum mechanical principles.

Homework Statement



For a 1D QM harmonic oscillator,

(a) the discrete energy states are nhw

(b) the discrete energy states are (n+0.5)hw

(c) the lowest energy state wave function is ~[tex]\exp^\frac{-\alpha^2\ x^2}{2}[/tex]

(d) the probability of finding the particle outside the classical limit is non-zero.

Homework Equations



The Attempt at a Solution



I think (b) and (c) are correct...by theory...

Should not (d) be also correct?--outside the classical limit=>inside quantum domain...

Yes, d is also correct. It is useful to do the calculation (one time in your life; and the sooner the better) to estimate the probability of finding the particle in its ground state outside the classical turning points.
