Experimental solution of the key problem of angular momentum transport by an electromagnetic radiation is presented. According to the classical electrodynamics, angular momentum of a circularly polarized light beam is localized near to the surface of the beam; however, the quantum theory predicts the spin angular momentum fills all body of the beam. We offer to interfere two beams, which pass through two half-wave plates, one of which is divided into two parts concentrically. When one of the parts is being rotated manually, the light frequency changes if this part absorbs angular momentum. It results in a movement of interference fringes, and makes it possible to verify theoretical predictions
