Amplitudes are expressed either as instantaneous values or mostly as peak values. Amplitude is the fluctuation or displacement of a wave from its mean value. With sound waves, it is the extent to which air particles are displaced, and this amplitude of sound or sound amplitude is experienced as the loudness of sound.
The interfering waves are A1sin(wt-kx) and A2sin(wt-kx+Î¸). Their resultant is a single wave with amplitude A. Denoting wt-kx by Î±, we have the sum. A1sin(Î±)+A2sin(Î±+Î¸)=Asin(Î±+Ï)*. sin(Î±+Î¸)=sin(Î±)cos(Î¸)+cos(Î±)sin(Î¸), and sin(Î±+Ï)=sin(Î±)cos(Ï)+cos(Î±)sin(Ï). Replacing into eq.
