We identify a region of a specific F(R) = RN gravity solution without external sources which is
isometric to the spacetime of colliding plane waves (CPW). The analogy renders construction and collision
of plane waves in F(R) = RN gravity possible. The geometry of the interaction region is equivalent to the
Reissner-Nordstr¨om (RN) one, however there is no Einstein-Maxwell (EM) source —this is made possible
by using the model of RN gravity and the parameter N > 1 creates the source. For N = 1, we naturally
recover the plane waves (and their collision) in Einstein’s theory.
