    Single slit diffraction bright fringe's width

    I tried plugging in values in the equation, that is how I found out that the separation of successive dark fringes increases as the order increases. Bright fringes exist between the minimas hence the width of the bright fringes decreases too. I have also seen and tried measure the width of...

    Single slit diffraction bright fringe's width

    According to my knowledge, the position of the dark fringes is given by asin(x)=m*lamda (sorry, I do not know how to type equations in here) tan(x)=d/L a=slit width x=angle of diffraction(?) m=no. of order d=distance from the central fringe L=distance between...

    Smoothing a rectified a.c current

    But why would the voltage be lower at the high end? If the voltage across the primary coil is constant, the voltage across in the secondary coil should also be the same. And since the capacitor and the load is in parellel, the voltage should stay the same at the higher end...

    Smoothing a rectified a.c current

    There is a fixed power a.c supply connected to a transformer which is then connected to a full wave rectifier and then to a load which is parrellel to a capacitor( for smoothing). If there is smoothing, the voltage across the load will be smoothed which will means that the average voltage...

    Confused with flow rate of water

    hmmm, i knew that, but, now i am designing a experiment and i do not know how to relate pressure to the flow rate of a liquid. What i am asking is that which formulae shld i use?? Since, both of them gave mi different proportionality, i can't possibly refer to both of them...

    Confused with flow rate of water

    By Bernoulli's law, if potential energy is constant, the work done, given by pV, where p is the pressure, V is the change in volume, is equal to the change in kinetic energy, 1/2mv^2. Does that mean that the flow rate of the liquid is proportionate to the root of the pressure applied?? If...

    Back EMF in Motors Explained - Need Help?

    the definition of EMF is the amonut of electrical energy converted from other forms of energy per unit charge. if you are wondering what's the diff from PD, then the definition of PD is the amount of electrical energy converted into other forms of energy. Basically emf is the force that...

    Can two equal swords break when clashing?

    Eh... when two identical swords "clang" together, is it possible that one of them breaks into two while the other one is still intact?? Thanks...sorry for asking such a question...watching too much anime you see...
