Speed of Sound Formula:
From: | To: |
The speed of sound formula calculates how fast sound waves travel through air based on temperature. The formula v = 331 + 0.6 × T provides the speed of sound in meters per second, where T is the temperature in degrees Celsius.
The calculator uses the speed of sound formula:
Where:
Explanation: The speed of sound increases by approximately 0.6 m/s for each degree Celsius increase in temperature, starting from 331 m/s at 0°C.
Details: Calculating the speed of sound is important in various fields including acoustics, meteorology, aviation, and engineering. It helps in designing sound systems, predicting weather patterns, and ensuring accurate distance measurements using sonar technology.
Tips: Enter the temperature in degrees Celsius. The calculator will compute the speed of sound in meters per second at that temperature.
Q1: Why does sound travel faster in warmer air?
A: Sound travels faster in warmer air because the molecules move more rapidly and transfer vibrational energy more efficiently.
Q2: What is the speed of sound at room temperature (20°C)?
A: At 20°C, the speed of sound is approximately 343 m/s (331 + 0.6 × 20 = 343 m/s).
Q3: Does humidity affect the speed of sound?
A: Yes, humidity slightly increases the speed of sound, but the temperature effect is much more significant. The formula v = 331 + 0.6 × T provides a good approximation for dry air.
Q4: How accurate is this formula?
A: This formula provides a good approximation for most practical purposes, though more complex formulas exist that account for humidity and atmospheric pressure.
Q5: Can this formula be used for other gases?
A: No, this specific formula is for dry air. Different gases have different molecular weights and properties that affect the speed of sound.
