Wavelength Formula:
From: | To: |
The wavelength formula (λ = v / f) calculates the wavelength of a wave by dividing its velocity by its frequency. For sound waves, this helps determine the physical length of one complete wave cycle.
The calculator uses the wavelength formula:
Where:
Explanation: The formula shows the inverse relationship between frequency and wavelength - as frequency increases, wavelength decreases, and vice versa.
Details: Calculating wavelength is essential in acoustics, audio engineering, and physics. It helps in designing audio systems, understanding sound propagation, and solving wave-related problems.
Tips: Enter velocity in meters per second and frequency in Hertz. Both values must be positive numbers greater than zero.
Q1: What is the speed of sound in air?
A: The speed of sound in air at room temperature (20°C) is approximately 343 m/s, but it varies with temperature and humidity.
Q2: How does temperature affect sound velocity?
A: Sound travels faster in warmer air. The velocity increases by about 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 doubles, wavelength halves, assuming constant velocity.
Q4: Can this calculator be used for light waves?
A: Yes, the same formula applies to light waves, but you would use the speed of light (299,792,458 m/s) as the velocity.
Q5: What are typical wavelength ranges for audible sound?
A: For human hearing (20 Hz to 20,000 Hz) in air, wavelengths range from about 17 meters (20 Hz) to 1.7 cm (20,000 Hz).
