    Smallest possible uncertainty in the positon of an electron

    sorry to be a bit daft, but still cat really get to the end. Let me summarize wat i understand so far first. The maximum possible uncertainty in E of a particle can be m_{0}c^{2}, because anything beyond that it would have enough energy to form another particle. and from...

    Smallest possible uncertainty in the positon of an electron

    ah ok thanks tahnks, that's a bit helpful. But i am still a bit unclear. That mean i don't have to do any rigourous maths like diffrenciations? and also i am not clear on the part they said, "when \Delta p exceeds mc, the uncertainty in energy is greater than mc^{2}" Why?

    Smallest possible uncertainty in the positon of an electron

    Homework Statement Show that the smallest possible uncertainty in the position of an electron whose speed is given by \beta=v/c is \Delta x_{min}=\frac{h}{4\pi m_{0}c}(1-\beta^{2})^{1/2} Homework Equations \Delta x \Delta p=\frac{h}{4\pi} p=mv= \frac{m_{0}}{\sqrt{1-\beta^{2}}}v...

    Diffraction grating for astronomy?

    Actually according to the prof, the grating was mistakenly bought this experiment. I suppose the original plan was to get a grating that would not require calibrating cos the lab manual never said anything about calibrating the grating. But since we end up with this, prof decides to turn this...

    Diffraction grating for astronomy?

    Hi, i am new here, so am not really sure wheather i am asking this qus at the right place. I have a Lab based qus. I just did the atomic spetra analysis using a diffraction grating, analysing hydrogen gas. But but when i calculate the wavelengths of the lines, its way off from the literature...
