Abstract
Quadratic Gravity is one of the modified theories of gravity; its action contains additional terms quadratic in Riemann tensor and its contractions. We study Kundt metrics, defined geometrically by admitting non-expanding, non-twisting and non-shearing null geodesic congruence, in the framework of Quadratic Gravity.
We examine the special cases, namely the pp-waves and VSI spacetimes. Equations of geodesic deviation are calculated to provide means of physical interpretation.
