A phenomenon, which can be observed only in transverse waves.(1) Refraction (2) Diffraction (3) Interferenc(4) Superposition

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
