About Wavelength Calculation
Wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats. It is usually determined by considering the distance between consecutive corresponding points of the same phase, such as crests, troughs, or zero crossings.
λ = v / f
Where:
λ = wavelength (meters)
v = wave velocity (meters/second)
f = frequency (Hertz)
Understanding wavelength is crucial in many fields including physics, engineering, astronomy, and music. Different types of waves have different velocities, which affects their wavelengths at the same frequency.
How the Wavelength Calculator Works
Our wavelength calculator uses the fundamental wave equation to determine wavelength based on frequency and velocity:
For Light Waves
Light waves travel at the speed of light in a vacuum (approximately 299,792,458 m/s). The calculator uses this constant velocity when you select "Light Waves".
For Sound Waves
Sound waves travel at different speeds depending on the medium. In air at 20°C, sound travels at approximately 343 m/s. The calculator uses this value when you select "Sound Waves".
For Water Waves
The speed of water waves depends on water depth and gravity. For deep water waves, the calculator uses a simplified model with velocity calculated as √(gλ/2π), where g is gravity (9.8 m/s²).
For Custom Waves
You can input any velocity value for custom wave types, allowing you to calculate wavelengths for various scenarios.
