Quantum Mechanics, a free particle prepared as a gaussian wavepacket
just taking a stab here but maybe there is a Fourier transform involved? Since the FT of a Gaussian is a Gaussian you would obtain another Gaussian (as u did in part b)... this may be of use http://www.maths.dur.ac.uk/~dma0wjz/QM/gaussian.pdf- TheNutyProfesr

Graduate Shortest wavelenght emmited by a black body
I agree with Tom, I would have thought it all depends on our detection abilities. To detect a very long wave we would require the detector to be at a temperature less than that of the source. To detect a very short wave we would require a detector that would somehow interact with the extremely...- TheNutyProfesr

Graduate Gravity and the double slit experiment
Firstly this can't work as we can't just 'çut off' gravity between one slit and the other (provided they are close by). Secondly, relativistic effects would kick in and we would be left with electrons going through the slits with different weights. Hence the pattern would be the close field...- TheNutyProfesr

Undergrad Uncertainty principle using 2 detectors
It all boils down to the math, plus its interpretation. Our interpretation of the math (the Copenhagen interpretation) is that no matter how one tries to measure the position and the speed+direction of a particle we cannot be more precise than some tiny number (planks constant (h)). Now this...- TheNutyProfesr

Graduate Double slit experiment with electrons
I think the central idea we are converging towards is entanglement. A key element of quantum mechanics, with the combination of the Heisenberg uncertainty principle, I can state that its not sufficient to describe the double/single slit exp. using classical analogies, we require rigorous math...- TheNutyProfesr

Graduate Harmonic Oscillator and Total Energy
hookes law applies to everyday objects like a mass on a spring, I assume that when you speak of vibration and rotation energies you are considering a molecule? If so, then 1/2KX^2 = E vib + E rot- TheNutyProfesr

Graduate If light is quantized, why are EM spectrum and Blackbody spectrum continuous?
''If light is quantized, and is given out in packets, why are the EM wave spectrum and the black body spectrum continuous? '' 1) Imagine a sine wave, via the Doppler shift we can stretch at and squish it. Therefore the spectrum will appear continuous. 2) There is also the matter of kinetic...- TheNutyProfesr

Undergrad Is the Electromagnetic Spectrum non-continuous?
I agree with DrClaude, (Doppler shift part specifically). Let's take the highest known energy photon with frequency f, now as the universe expands and the rate accelerates the frequency will slowly decrease. Hence a single photon can exhibit infinite energies as it morphs with time. This...- TheNutyProfesr
