I have been studying Fourier Optics and I have a basic conceptual question. I understand the mathematics of how to perform Fourier Transforms however the part of this topic I seem to have missed is why the action of a lens on light is the same as performing a Fourier Transform on the functional...
The reference book I am working from (Measurements and their Uncertainties by I.G. Hughs & &. Hase) defines reduced chi squared as:
χ\nu2=\frac{1}{\nu}Ʃ\frac{(yobs-yexp)2}{α2}
where α is the uncertainty on the individual yobs.
and \nu is the number of data points minus your degrees of...
Sorry exp means expected/theoretical value.
The experiment deals with the resistivity of a super conductor at different temperatures. I have the characteristic result where the resistivity is zero until reaching a critical temperature, then a rapid near vertical increase followed by a...
So I have been analyzing data a took in an experiment recently and have been using a chi squared as a "goodness of fit" test to against a linear model.
I am using excel and used the LINEST function (least square fitting method) to get an idea for a theoretical gradient and intercept for my...
