a pebble is dropped into a still pond. ripple waves travel outward through the water. which interaction…

Brief Explanations:

When ripple waves travel through water, they are transmitted through the water medium. Absorption would mean the energy of the waves is taken in by the water and dissipated, which isn't the main process here. Reflection would occur if the waves hit a boundary and bounce back. But the main interaction as the waves move outward through the water is transmission of the wave energy.

Answer:

transmission
