In the limit as a pulse width (τ) for a given frequency (υ) goes to infinity, the frequency spread generated by the fft of the waveform goes to what? explain. if one wants to deliver radiation with a given frequency of very high precision to a sample, does the pulse need to be ‘short’ or ‘long’ ? explain. consider two arbitrary waveforms: one waveform is very sinusoidal in nature, the other is very “step-ish” and had non-smooth appearance. what can be said about the relative spread or distribution of sin/cos functions needed to reconstruct these waveforms?

Neutrons are placed in a magnetic field with magnitude 2.30 t. part a part complete what is the energy difference between the states with the nuclear spin angular momentum components parallel and antiparallel to the field? δe δ e = 2.77×10−7 ev previous answers correct part b part complete which state is lower in energy: the one with its spin component parallel to the field or the one with its spin component antiparallel to the field? which state is lower in energy: the one with its spin component parallel to the field or the one with its spin component antiparallel to the field? parallel antiparallel previous answers correct part c part complete how do your results compare with the energy states for a proton in the same field (δe=4.05×10−7ev)? how do your results compare with the energy states for a proton in the same field this result is smaller than but comparable to that found in the example for protons. this result is greater than but comparable to that found in the example for protons. previous answers correct part d the neutrons can make transitions from one of these states to the other by emitting or absorbing a photon with energy equal to the energy difference of the two states. find the frequency of such a photon. f f = mhz previous answersrequest answer incorrect; try again; 5 attempts remaining
