1. What Is The Speed Of Sound In Mph?

The speed of sound in miles per hour (mph) varies with temperature in the atmosphere. At 20°C (68°F), sound travels at approximately 767 mph. This speed increases with higher temperatures and decreases with lower temperatures.

2. How Does The Calculator Work?

The calculator uses the speed of sound equation:

Where:

• \( v \) — Speed of sound in mph
• \( T \) — Temperature in °C

Explanation: The equation calculates how the speed of sound changes with temperature relative to the baseline speed of 767 mph at 20°C.

3. Importance Of Speed Of Sound Calculation

Details: Calculating the speed of sound is important in aviation, meteorology, acoustics, and various engineering applications where sound propagation needs to be accurately predicted.

4. Using The Calculator

Tips: Enter the temperature in degrees Celsius. The calculator will compute the corresponding speed of sound in miles per hour at that temperature.

5. Frequently Asked Questions (FAQ)

Q1: Why does the speed of sound change with temperature?
A: Sound travels faster in warmer air because the molecules move more rapidly and transmit vibrations more quickly.

Q2: What is the speed of sound at 0°C?
A: At 0°C, the speed of sound is approximately 741 mph using this calculation method.

Q3: Does humidity affect the speed of sound?
A: Yes, humidity has a minor effect, but temperature is the primary factor affecting sound speed in air.

Q4: How accurate is this calculation?
A: This provides a good approximation for most practical purposes, though specialized applications may require more complex formulas.

Q5: Can this calculator be used for other mediums?
A: No, this calculator is specifically for sound traveling through air at standard atmospheric pressure.
