identifying factors that affect wave speed\nwhat would happen to the speed of a sound wave if it moved from ocean water to air?\nwhat would happen to the speed of a sound wave if it moved from a cooler room to a warmer one?

Answer

Explanation:

Step1: Recall sound - wave speed in different media

Sound travels faster in denser media. Ocean water is denser than air. So, when a sound wave moves from ocean water to air, its speed decreases.

Step2: Recall sound - wave speed and temperature

The speed of sound in a gas is directly proportional to the square - root of its absolute temperature. When moving from a cooler room to a warmer one, the temperature increases. So, the speed of the sound wave increases.

Answer:

  1. The speed of the sound wave would decrease.
  2. The speed of the sound wave would increase.
