which is the best analogy of a wave?\na wave is like building a ramp.\na wave is like shaking a hand.\na…

Brief Explanations:

A wave is a disturbance that propagates through a medium. Water rippling in a pond shows the characteristic of a wave as it spreads out from a point of disturbance (like a pebble dropped in the pond) through the water (the medium). Building a ramp is a static structure - no propagation. Shaking a hand is a one - time interaction. Knocking down a building is a destructive, non - wave - like action.

Answer:

A wave is like water rippling in a pond.
