2. Superposition of waves moving in the same direction. Two traveling waves with the equations y₁ = A sin(kx-w₁t) and y₂ = A sin(k₂x - w₂t + p) are present in a medium. (a) Find the equation of the wave function resulting from the superposition of the two waves. (b) Describe the resulting superposition wave. Can it produce stationary waves? (c) If the speed of the waves in the medium is 6 m/s, and each wave has a wavelength of 2 m and 3 m, find the superposed wave function. Draw a wave function at t = 0 s if the phase difference (i) = 0°, (ii) = 90°, and (iii) 4 ) = 180°. (d) As in point (c), but both waves have the same wavelength, say 2 m.
