Wave Formula:
| From: | To: |
The wave formula v = fλ describes the relationship between the speed of sound (v), frequency (f), and wavelength (λ). This fundamental equation applies to all types of waves, including sound waves.
The calculator uses the wave formula:
Where:
Explanation: The speed of sound equals the product of frequency and wavelength. This relationship holds true for sound waves propagating through any medium.
Details: Calculating the speed of sound is essential in various fields including acoustics, audio engineering, sonar technology, and musical instrument design. It helps determine how sound waves propagate through different media.
Tips: Enter frequency in Hertz (Hz) and wavelength in meters (m). Both values must be positive numbers greater than zero for accurate calculation.
Q1: Does the speed of sound vary in different media?
A: Yes, the speed of sound varies significantly in different media. It travels faster in solids than in liquids, and faster in liquids than in gases.
Q2: What is the typical speed of sound in air?
A: At 20°C, the speed of sound in dry air is approximately 343 m/s. This value changes with temperature, humidity, and air pressure.
Q3: How does temperature affect the speed of sound?
A: The speed of sound increases with temperature. For air, the speed increases by about 0.6 m/s for each degree Celsius increase in temperature.
Q4: Can this formula be used for light waves?
A: While the basic wave equation v = fλ applies to all waves, light is an electromagnetic wave and its speed in vacuum is constant at approximately 3×10⁸ m/s.
Q5: What are practical applications of this calculation?
A: This calculation is used in designing acoustic spaces, developing audio equipment, calculating distances in sonar systems, and understanding musical instrument acoustics.
