We present a novel form of quartic reciprocal functional equations in this work. The intriguing fact that harmonic points arise in projective geometry inspired our work to examine this new equation. The stability of this equation is established using the fixed point method. Additionally, several upper bounds are considered to produce stability results. As an application of this equation, it is connected to the Rayleigh scattering formula. The arguments of this equation are connected to harmonic points at the conclusion of this research.
