Answer:

ripple marks

Step-by-step explanation:

Undulation is defined as the to and fro wavelike motion in a fluid or elastic medium.

Undulation in sandy material is called ripple marks because ripple marks are the sediments of rocks that show wavy structure at its surface due to agitation by water and wind.

Hence, the correct answer is "ripple marks".
