Question

A sound wave propagating to the right has a frequency of 1.0 kHz and an amplitude of 15 nm. What is an equation, $LaTeX: \psi\left(t,x\right)$ ψ(t,x), of the wave that describes its behavior? Assume the speed of sound is 344 m/s and write your answer with only SI units.

Answer 1

Representation of sound ware 4 (t, x) = F(x-ot). 'F' represent form of wave ov, 464x) = A fin (Ka-wt) . it take sinusoidal forms of wave where, A= amplitude nm MERT wa za f = 2ax 1x10 Hz K = 2 = 20 ľ But V-fx =) to le de 343 7 344 IXTO Hence, | 4C+2) = 15x15" sin (2-12-2osh +)
