WebThe speed of any periodic wave is the product of its wavelength and frequency. v = λf. The speed of any electromagnetic waves in free space is the speed of light c = 3*10 8 m/s. … WebFor a coaxial conductor, the wave speed formula ends up being very simple: v = 1 μ ϵ For a relative dielectric constant ( ϵ / ϵ 0) of 3, one calculates a velocity of 58% of the speed of light. Finally, your elastic ball analogy is good to zeroth order, but I don't think you can use it to think about propagation velocity.
