the harmonic wave equation is given by y(x,t)=Rsin{2[itex]\pi[/itex]/[itex]\lambda[/itex](vx-t)+[itex]\phi[/itex]}(adsbygoogle = window.adsbygoogle || []).push({});

where R is amplitude

[itex]\lambda[/itex]is wavelength

v is velo of wave

[itex]\phi[/itex] is initial phase.

Could you please tell as well as explain me what are the parameters x and t where there in units of length and time respectively.
