Which is TRUE concerning the speed of sound in water?

🔍 Key Concepts

• Speed of sound in different media (air vs. water vs. steel) • Typical numerical value of sound speed in air at sea level and room temperature • Approximate speed of sound in seawater used for sonar and depth sounders

💭 Think About

• First recall the usual speed of sound in air (in meters per second or feet per second). Then recall the commonly used value for speed of sound in seawater used in navigation/sonar tables. • Compute the ratio: $\text{speed in water} \div \text{speed in air}$ using the approximate values you remember, then compare that ratio to the options given. • Think about why sound travels faster in denser, less compressible media like water, and whether the increase is modest or several times greater.

✅ Before You Answer

• Know a reasonable approximate speed of sound in air (about 340 m/s or 1,100 ft/s at standard conditions). • Know a commonly used approximate speed of sound in seawater (around 1,500 m/s or 4,900–5,000 ft/s used for sonar/depth calculations). • Before choosing, divide the water value by the air value to check which multiple (1.5, 2.5, 3.5, or 4.5) is closest to your ratio.
