A longitudinal wave is represented by the equation z(z, t) = −2.0 cm sin(1,200 rad/s t − 20 m−1 z). Another longitudinal wave is represented by the equation z(z, t) = +2.0 cm sin(1,200 rad/s t + 20 m−1 z). What is the equation that represents the superposition of the two waves?

A transverse periodic wave is represented by the equation y(x, t) = 1.50 cm sin(1,500 rad/s t − 10.0 m−1 x). Another transverse wave is represented by the equation y(x, t) = 1.50 cm sin(1,500 rad/s t + 10.0 m−1 x). What is the equation that represents the superposition of the two waves?

A longitudinal wave travels on a slinky or any long spring. The wave is represented by the equation z(z, t) = 1.2 cm cos(1800 rad/s t + 60 m−1 z). What are the wavenumber and direction of propagation of the wave?

A longitudinal wave travels on a slinky or any long spring. The wave is represented by the equation x(x, t) = 2.10 cm cos(2000 rad/s t + 40.0 m−1 x). What is the velocity of the wave?

Many interesting wave phenomenon in nature cannot just be described by a single wave, instead one must analyze complex waveforms in terms of a combinations of many travelling waves. To analyze such wave combinations, we make use of the principle of superposition which states that if two or more travelling waves are moving through a medium and combine at a given point, the resultant displacement of the medium at that point is sum of the displacement of individual waves. Two pulses travelling on the same string are described by\(y_{1}=\frac{5}{(3 x-4 t)^{2}+2} \text { and } y_{2}=\frac{-5}{(3 x+4 t-6)^{2}+2}\) The time when the two waves cancel everywhere
