Consider two sinusoidal waves: fi = A1 cos (kz – wt + ø1) and f2 = A2 cos (kz – wt + 02). We can write their complex forms as fi =Aje(kz-wt+61) = Ã¡eï(kz-wt) f2 =Aze(kz-wt+62) = Ãze³(kz-wt) where the complex amplitudes Ã1 = Ajeø1 and Ã, = Azeió2 Now suppose we want to combine the two: fs = fi + f2 = Ãze(k3:-w3t) = Azeiøs ei(kzz=wzt) Find expressions for A3, $3, k3, and w3.
A periodic vibration at x = 0, t = 0 displaces air molecules along the x direction by smax = 3.2E-05 m. The motion produces a sound wave that travels at a velocity of v = 336 m/s with a frequency of f = 120 Hz. Take the density of air as ρa = 1.20 kg/m3. Calculate the wavelength λ of the sound wave, in meters. Calculate the wavenumber k of the sound, in radians per meter. Calculate the angular frequency of the sound ω, in radians per second.
