Sound Wavelength Formula:
From: | To: |
The sound wavelength formula relates the wavelength of a sound wave to its frequency and the speed of sound in the medium. It is fundamental in acoustics and wave physics.
The calculator uses the wavelength equation:
Where:
Explanation: The wavelength is inversely proportional to frequency - higher frequency sounds have shorter wavelengths.
Details: Knowing the wavelength is essential for designing acoustic spaces, audio equipment, and understanding how sound interacts with objects and environments.
Tips: Enter the speed of sound in your medium (343 m/s for air at 20°C is typical) and the frequency of interest. Both values must be positive numbers.
Q1: What is the typical speed of sound in air?
A: Approximately 343 m/s at 20°C (68°F), but it varies with temperature, humidity, and altitude.
Q2: How does wavelength relate to pitch?
A: Higher pitch sounds have higher frequencies and therefore shorter wavelengths.
Q3: Does wavelength change in different media?
A: Yes, since the speed of sound changes in different media, the wavelength will change even if frequency stays constant.
Q4: What's the wavelength range for human hearing?
A: For audible frequencies (20Hz-20kHz) in air, wavelengths range from about 17 meters to 1.7 cm.
Q5: Why is wavelength important in speaker design?
A: Speaker size needs to be appropriate for the wavelengths it's reproducing - larger speakers handle longer wavelengths (lower frequencies) better.
