Wavelength from Speed & Frequency
Formula
v = fλ, where v is wave speed in m/s, f is frequency in Hz, and λ (lambda) is wavelength in meters.
Frequently Asked Questions
What determines wave speed?
Wave speed depends on the medium through which the wave travels. For example, sound travels faster in water than in air. The speed is determined by the properties of the medium, not by the frequency or amplitude of the wave.
What is the speed of light?
The speed of light in a vacuum is approximately 299,792,458 m/s (about 3 × 10⁸ m/s). In other media, light travels slower depending on the refractive index of the medium.
