    Blackbody radiation

    It is indeed odd. But even more surprisingly i found what it refers to after reading the next chapter. After some pages it is indicated that the constant sigma actually refers to the damping constant (as the system is considered as damped oscillator since it emits radiation) but still i don't...

    Blackbody radiation

    Thank you very much for your time. actually that is the part i didn't understand. because i don't see any relation between the formula for the conseravation of energy and σ , in the book it just appears suddenly and then the author concludes the final equation (the differential equation) by...

    Blackbody radiation

    consider energy for a damped electric oscillator . ("f" indicates the dipole moment of the oscillator) in the absence of the damping force U= \frac{1}{2}kx^2 +1/2 (\frac{d^2x}{dt^2}) ^2 and the energy conservation tells us dU=0. but if there is damping force we get the following...
