Brody and Ethel are arguing about waves. Brody says that waving his hand back and forth is a scientific wave. Ethel says that it is not. Which statement best describes who is correct?

A scientific wave transfers energy from one place to another, usually through a medium or through space. Brody’s hand moving back and forth is motion, but it does not carry energy away from the hand as a wave does. So Ethel is correct because energy is not carried from one place to another.
