Wave Speed Formula:
| From: | To: |
The wave speed formula (v = f × λ) calculates the speed of a wave by multiplying its frequency (f) by its wavelength (λ). This fundamental equation applies to all types of waves, including sound waves, light waves, and water waves.
The calculator uses the wave speed equation:
Where:
Explanation: The equation shows the direct relationship between wave speed, frequency, and wavelength. As frequency or wavelength increases, wave speed increases proportionally.
Details: Calculating wave speed is essential in various fields including acoustics, optics, telecommunications, and oceanography. It helps determine how quickly waves travel through different media and is fundamental to understanding wave behavior.
Tips: Enter frequency in Hertz (Hz) and wavelength in meters (m). Both values must be positive numbers greater than zero for accurate calculation.
Q1: What units should I use for the calculation?
A: Frequency should be in Hertz (Hz) and wavelength in meters (m) to get wave speed in meters per second (m/s).
Q2: Does this formula work for all types of waves?
A: Yes, the formula v = f × λ applies to all wave types, though the actual speed may vary depending on the medium through which the wave travels.
Q3: How does the medium affect wave speed?
A: Wave speed depends on the properties of the medium. For example, sound travels faster in water than in air, and light travels slower in glass than in vacuum.
Q4: Can I calculate frequency or wavelength if I know the wave speed?
A: Yes, you can rearrange the formula: f = v/λ for frequency, or λ = v/f for wavelength.
Q5: What are typical wave speed values?
A: Sound waves in air travel at about 343 m/s, light waves in vacuum at 299,792,458 m/s, and ocean waves typically between 5-25 m/s depending on conditions.
