3 A quantum harmonic oscillator consists of a 100-gram mass
attached to a spring with spring constant 60 N/m. This system, while
ocillating, lowers its energy by dropping down one quantum state
(quantum number n decreases by 1). If the energy that the oscillator
loses is carried off by a photon, what would be the wavelength of
this photon? Give your answer in meters. The answer does not
depend on the oscillator's initial quantum state.

Suppose that at a given time a quanton has the (unrealistic) wavefunction shown. If we per-
form an experiment to locate the quanton at that time, what is the probalitiy that the result
will be greater than zero? Explain your reasoning. (Assume that y(x) = 0 everywhere out-
side the region shown. The size of the vertical and horizontal scales in not relevant.)

Following an experiment we observe the diffraction pattern shown (below) left. A slice through the center of this pattern (dashed yellow line) yields the interference pattern shown on the right, wherein the first dark spot is located 3.15 cm from the centerline. Using this information calculate the lattice constant (interatomic spacing) of the crystal. 3.15 cmarrow_forwardPlease answer the following question :1. After being scattered by an electron, the wavelength of the x-ray changes in what way? Does that scattered x-ray gain or lose energy? Is this what classical electromagnetic theory predicts? 2. What would the shapes of the graphs be if the classical explanation was the correct explanation? 3. Examine the graph at the lower right. Are the deflected x-rays uniformly distributed over all the scattering angles? Does the shape of that distribution change for different incoming x-ray energies?arrow_forward
