    I What is the indefinite integral of Bessel function of 1 order (first k

    The recurrence relations help writing the integrals of Bessel functions in terms of other Bessel functions of other orders.

    I What is the indefinite integral of Bessel function of 1 order (first k

    Hi When we find integrals of Bessel function we use recurrence relations. But this requires that we have the variable X raised to some power and multiplied with the function . But how about when we have Bessel function of first order and without multiplication? How should we integrate it ?

    I Black body radiation -- Some basic questions to aid my understanding

    So the way I understand it is correct.The photons escape out of the sun as if the they escape from the hole of a hot cavity after being trapped inside.

    I Black body radiation -- Some basic questions to aid my understanding

    Thanks for replying I understand it now a little better . Could you please recommend some books for a deeper understanding of blackbody radiation . You didn't tell me whether the way I understand it is correct or not ..ie,the waves escape from interatomic spaces .

    I Black body radiation -- Some basic questions to aid my understanding

    Hi I am currently taking a physics course and studying black body radiation.I have already seen a good number of books , but I have a lot of unanswered questions. -What does the black body radiation, which is approximately the radiation of the sun, has to do with standing waves inside a cavity...

    How to Fix Limits of Integration for Gamma Integral #6?

    Ok I will ask my professor Incomplete gamma function is beyond the scope of my course . May be it was a mistake to give us it in the exercises on gamma function

    How to Fix Limits of Integration for Gamma Integral #6?

    Thanks for help You didn't use the gamma function The error function is not the subject of my course . These exercises are on gamma function Please make it in terms of gamma function.

    How to Fix Limits of Integration for Gamma Integral #6?

    Hi I have a gamma integral in which it is not obvious how I can fix the limits of integration in order to match the standard form of gamma function.I just need someone to tell me how to fix them. I mean the integral number 6 in the picture. You can see my attempt in the PDF .

    I Riddle: Where is Epsilon in Bohr Model of Atom?

    Hi curious people Today i had a lecture about bohr model of the atom .we know that the total energy of electron in orbit is minus e squared divided by 8 pi times epsilon times R of the orbit . this is written in my book and i agree with this .But when the author writes a formula for an emitted...
