                                 FOURIER SERIES A Fourier series is defined as an expansion of periodic function or represent in a series of sines and cosines       where   Function must satisfy the Dirichlet condition. The fourier series expansion in the interval -L to L is given by <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-1688730777350635"      crossorigin="anonymous"></script>                       Half-Range Fourier Series                          ...

           COMPTON SCATTERING       The scattering of photon of energy h n by an electron rest mass m 0 After scattering photon scattered at angle   q   and electron scattered at angle   f . The scattered photon has energy hv ¢ and electron have energy E.    From the conservation of energy   loss in photon energy = gain in electron energy   hv - hv ¢ = KE The momentum of photon is given    P=E/c = hv/c From conservation of momentum in x direction  ;     hv+0 =( hv ¢/ c)  cos  q +   P  cos  f   conservation of momentum in y direction ;      0= ( hv ¢/ c) sin  q + P  sin  f solving above 2 equation, we got   λ’-λ= (1-cos q )                λ’-λ = λ c (1-c...
