The intensity of a sound wave is also related to the pressure amplitude Δp:$I = \frac{(\Delta p)^{2}}{2 \rho v}$where ρ is the density of the medium in which the sound wave travels and...The intensity of a sound wave is also related to the pressure amplitude Δp:$I = \frac{(\Delta p)^{2}}{2 \rho v}$where ρ is the density of the medium in which the sound wave travels and v w is the speed of sound in the medium. The relationship for the frequencies for the string is the same as for the symmetrical boundary conditions of the pipe, with the length of the pipe replaced by the length of the string and the velocity replaced by v = √FTμ.
