Question 1.

In quantum mechanics, when we say a particle is "free" we mean that no potential acts upon it.

       True
       False

Question 2.

The first excited state is the state with energy just above the ground state.

       True
       False

Question 3.

The energy levels in the simple harmonic oscillator or evenly spaced.

       True
       False

Question 4.

The probability of transmission for a particle impacting on a barrier potential is proportional to the wave function.

       True
       False

Question 5.

In barrier penetration, the tunneling effect is only observed for the wave function. That is, a particle can never tunnel through solid objects.

       True
       False

Question 1.

The probability for finding a particle in a particular location is equal to the integral over

      a. the normalization of the particle.
      b. the modulus squared of the particle's wave function.
      c. the quantum wave function of the particle.
      d. the de Broglie wavelength of the particle.

Question 2.

When two quantum mechanical states have the same energy, the states are

      a. undefined.
      b. degenerate.
      c. not normalizable.
      d. excited.

Question 3.

The region where the potential is greater than the energy of the particle is called

      a. the barrier region.
      b. ground state region.
      c. the classically forbidden region.
      d. zero-probability region.
