Variables
vwave speed (m/s)
ffrequency (Hz)
lambda[λ]wavelength (m)
Description
What is this formula?
The Wave Speed formula relates the propagation speed of a wave to its frequency and wavelength. It is one of the fundamental equations of wave mechanics and applies to mechanical, acoustic, and electromagnetic waves.
When to use it
Use this formula when calculating wave propagation, determining wavelength from frequency, or analyzing vibrations and oscillations.
Example
Given:
f = 440 Hz
λ = 0.78 m
Formula:
v = fλ
Substitution:
v = 440 × 0.78
v = 343.2 m/s
Result:
v = 343.2 m/s
Applications
