Wavelength Formula:
| From: | To: |
The wavelength formula calculates the distance between consecutive points of the same phase in a wave. For sound waves, it relates the wavelength (λ) to the frequency (f) and velocity (v) of the wave through the medium.
The calculator uses the wavelength formula:
Where:
Explanation: The formula shows that wavelength is inversely proportional to frequency - higher frequencies result in shorter wavelengths when velocity is constant.
Details: Calculating wavelength is essential in acoustics, audio engineering, and physics. It helps determine how sound waves behave in different environments, interact with objects, and are perceived by listeners.
Tips: Enter frequency in Hertz (Hz) and velocity in meters per second (m/s). Standard sound velocity in air at 20°C is approximately 343 m/s. All values must be positive numbers.
Q1: What is the standard speed of sound in air?
A: The speed of sound in air at 20°C is approximately 343 meters per second, but it varies with temperature, humidity, and altitude.
Q2: How does temperature affect sound velocity?
A: Sound travels faster in warmer air. The velocity increases by approximately 0.6 m/s for each degree Celsius increase in temperature.
Q3: What is the relationship between frequency and wavelength?
A: Frequency and wavelength have an inverse relationship. When frequency increases, wavelength decreases, and vice versa, assuming constant velocity.
Q4: Why is wavelength important in audio applications?
A: Wavelength determines how sound waves interact with objects and spaces. It affects diffraction, reflection patterns, and is crucial for speaker design and room acoustics.
Q5: How does sound velocity change in different media?
A: Sound travels faster in solids than liquids, and faster in liquids than gases. For example, sound travels at about 1480 m/s in water and 5000 m/s in steel.
