Definition: Undulated is a term in physics and engineering used to describe an object that has a slight deflection or curvature when viewed from above. This effect arises due to the presence of a layer of material between two surfaces, such as a plate or a surface with a small indentation. The term "undulated" refers to the way in which this material is distributed on the surface, and can be used to describe any object that has a slight deflection when viewed from above.
