What does undulated mean?
“Undulated” is the past tense and past participle of “undulate,” meaning to move or rise and fall in smooth, wave-like motion. It is especially used for surfaces, landscapes, or lines that have a succession of gentle curves, as in “the road undulated across the moor,” and it can also describe movement resembling rolling or rippling waves. In figurative writing, the verb can evoke graceful, continuous variation, such as a voice “undulating” between high and low notes or a crowd “undulating” in response to a speaker. The word is formal and literary rather than everyday, but it remains common in descriptions of terrain, fabric, water, and visual design. Its value lies in conveying rhythmic movement more precisely than a general word such as “moved.” Because it follows the regular English pattern of “undulate” plus “-ed,” its tense and aspect are clear, while its Latin-derived sound gives it an elegant, classical character.
Moved in a smooth, wave-like manner, especially by rising and falling in gentle, rhythmic curves.
"The surface of the lake undulated in the strengthening breeze."
This is the past tense and past participle of undulate. It is formal and literary and is often used to describe movement that follows a smooth, flowing rhythm.
Having a wavy form or a series of gentle rises and falls.
"She followed the undulated path toward the coast."
In this use, undulated commonly follows the noun it modifies and describes a surface, terrain, line, or other form.
Undulatus meant “wavy” in Latin, so to undulate is, quite literally, to move like a wave.

Where does undulated come from?
English “undulate” was borrowed in the early 17th century from Latin undulatus, a past participle meaning “wavy.” Latin undulare means “to wave” or “move in waves,” and it derives from undula, a diminutive of unda, meaning “wave.” The same Latin root produced English words including “undulation,” “undulatory,” and “undulant.”
