Q2 ). A continuous sinusoidal longitudinal wave is sent along a coiled spring from a vibrating source attached to it, The frequency of the source is 25 Hz , and the distance between successive rarefactions in the spring is 24 cm . If the maximum longitudinal displacement of a particle in the spring is 0.30 cm . Find the \( (\boldsymbol{a}) \), amplitude \( \left(s_{m}\right)(\boldsymbol{b}) \), wavelength \( (\lambda)(\boldsymbol{c}) \), wave number \( (k)(\boldsymbol{d}) \), angular frequency \( (\boldsymbol{\omega}) \) (e). wave speed.
