Science: When A Mother Takes Charge

Watching ducklings swim in a line behind their mother is an endearing sight, but it also unveils a fascinating physical principle.

As the mother moves through the water, she breaks the surface tension and generates waves that benefit her ducklings. While a lone duckling must expend more energy to move through the water, following the mother creates a phenomenon known as wave interference.

This process, specifically destructive interference, allows the waves generated by the mother to gently push the ducklings, reducing their effort. This effect is passed down the line, enabling each duckling to use less energy and swim more efficiently. A perfect example of how physics operates in nature to enhance survival.
