Dear all,
many people refer to the CMB anisotropy picture by WMAP or Plack and call it acoustic waves. I thought there is the anisotropy of the CMB radiation plotted, what exactly can I imagine to be the acoustic wave of it?
Secondly, what exactly is plotted n the famous plot where the wave number l is on the x-axis and I got those 7 peaks, where observers fit the whole cosmological parameters.
thank you very much
