Which term describes a reflected sound wave?

  1. Ebb Tide

  2. Echo

  3. Eclipse

  4. Ecology

The correct answer is: Echo

An ebb tide is the period between high tide and low tide, and is not related to sound at all. Eclipse refers to the blocking of light from the sun or moon, and ecology is the study of organisms and their environment. Only an echo refers to a reflected sound wave, making it the correct answer.
