1. What is Speed Of Sound In Feet Per Second?

The speed of sound in feet per second represents how fast sound waves travel through a medium, typically air. At 20°C (68°F), sound travels at approximately 1125 feet per second in dry air.

2. How Does the Calculator Work?

The calculator uses the formula for speed of sound in air:

Where:

• \( v \) — Speed of sound (ft/s)
• \( T \) — Temperature in Celsius (°C)

Explanation: The speed of sound increases with temperature because warmer air has higher molecular motion and better sound transmission.

3. Importance of Speed Of Sound Calculation

Details: Calculating sound speed is crucial for audio engineering, acoustics, military applications, meteorology, and determining distance in sonar and radar systems.

4. Using the Calculator

Tips: Enter temperature in Celsius. The calculator will compute the speed of sound in feet per second for that temperature.

5. Frequently Asked Questions (FAQ)

Q1: Why does sound speed vary with temperature?
A: Sound travels faster in warmer air because the air molecules have higher kinetic energy and can transmit sound vibrations more quickly.

Q2: What is the speed of sound at room temperature?
A: At 20°C (68°F), sound travels at approximately 1125 feet per second or 343 meters per second in dry air.

Q3: How does humidity affect sound speed?
A: Humidity has a minor effect on sound speed. Sound travels slightly faster in humid air than in dry air at the same temperature.

Q4: Does sound travel faster in water or air?
A: Sound travels about 4.3 times faster in water (approximately 4800 ft/s) than in air due to water's higher density and elasticity.

Q5: What is the speed of sound at absolute zero?
A: At absolute zero (-273.15°C), the speed of sound would theoretically approach zero as molecular motion ceases.
