QM1.4: The Free Particle - A Gaussian Wave Packet

With our aim of localizing the wave function, we use a Gaussian wave packet in the form of φ(k) for our Fourier Transform. The values of the function φ(k) will be used as the amplitudes of the solutions that when superimposed, interfere constructively in a finite region.

Nice explanation! There was a little mistake, though. When you use the normalization condition on the wavefunction psi you can express it as a normalization condition of the coefficients phi. This condition tells you that the absolute value squared of phi, integrated along k must be equal to (2*pi)^(1/2) (Not 1).

well done...............only saw one mistake

Thanks a lot. i finished my B.Sc. in Theoretical Physics in 2006 then i got married and had two kids so i forgot almost everything i learned in college. Thank you so much for posting these videos. you helped me remember the subject i always loved. :)

Great video! You helped me immensely with my extra credit problems for my modern physics class.

though im not that adept in quantum physics..you still make it sound interesting!! You make it sound understandable!

Great Videos
