The figure shows the circular wave fronts emitted by two sources. The wavelength of the two identical waves is 4.2 m. What is the path-lenngth difference at point R, in meters? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answe it is already given in the question statement.
