please reexplain this paragraph two-beam interference with the double exciter:the circular waves generated by the double exciter are super- posed at the points where they meet. The areas with no wave motion indicate cancellation (minima).the minima and maxima are positioned along hyperbolas with the excitation centers as focal points. the relationships given in the section h0rinciples” for the positions of the hyperbolas are confirmed experimentally.The interference patterns are determined by the distance be- tween exciters, and by the wavelength. the number of hyperbo- las increases with the exciter spacing and the wavelength, and the hyperbolas open further.
Determine the probability that a photon is detected at the location of the first minimum of a 3-slit grating if the thrid slit is closed.

What is the resulting amplitude if the first amplitude is eliminated?)
