WebAnd also reasoned that matter would follow the same equation for wavelength as light namely, λ = h / p Where p is the linear momentum, as shown by Einstein. Derivation de Broglie derived the above relationship as follows: 1) E = hν for a photon and λν = c for an electromagnetic wave. 2) E = mc 2, means λ = h/mc, which is equivalent to λ = h/p. WebThe speed v v of a wave is constant for any unchanging medium, so frequency and wavelength are inversely proportional. The wave speed equation is not a new equation, it’s just a different way of writing. v = \dfrac {\Delta x} {t} v = tΔx. which we can rearrange to get. \Delta x = vt Δx = vt.
