This powerpoint slide presentation is to help individuals derive the Intensity formula for sound waves and understand the relation between amplitude and intensity.
Kinetic Energy= (1/2)mv2
At maximum velocity, the total
amount of energy is equal to
kinetic energy.
Therefore, E=(1/2)m(vmax)2
From SHM, vmax=Aω
Hence, E=(1/2)m(Aω)2
E=(1/2)(ρV)(Aω)2
