Questions & Step-by-Step Solutions
If a sound wave travels from air into water, how does its speed change?
Step 1: Understand that sound travels through different materials at different speeds.
Step 2: Know the speed of sound in air, which is about 343 meters per second (m/s).
Step 3: Know the speed of sound in water, which is about 1482 meters per second (m/s).
Step 4: Compare the two speeds: 1482 m/s (water) is greater than 343 m/s (air).
Step 5: Conclude that when sound moves from air into water, its speed increases.
