כיצד לחשב את Wave Speed
learn.whatIsHeading
Wave speed is the rate at which a wave propagates through a medium. The fundamental wave equation v = fλ relates wave speed (v), frequency (f), and wavelength (λ). It applies to all wave types: sound, light, radio, water, seismic, and string waves. For electromagnetic waves in vacuum, v = c = 3 × 10⁸ m/s (the speed of light).

- 1v = f × λ (wave speed = frequency × wavelength)
- 2f = v / λ (frequency = speed / wavelength)
- 3λ = v / f (wavelength = speed / frequency)
- 4Speed of sound in air at 20°C ≈ 343 m/s
- 5Speed of light in vacuum = 299,792,458 m/s ≈ 3×10⁸ m/s
