Question

An echo is sound that returns to you after being reflected from a distant surface (e.g., the side of a cliff). Assuming that the distances involved are the same, an echo under water and an echo in air return to you ________.

Answer 1

Answer:

At different times

Explanation:

The echo returns at different times, but faster in water. This is because water particles are bound closer and this makes them transmit vibration energy from one particle to the next quickly. An echo is a sound wave and sound waves are longitudinal waves that occur by the collision of particles to move the vibrations along, and this is why they move slower in air.

At different times is the answer.
