The equation of a sound wave in air is given by `trianglep=(0.02)sin[(3000)t-(9.0)x]`, where all variables are is SI units. (a) find the frequency, wavelength and the speed of sound wave in air. (b) If the equilibrium pressure of air is `1.01xx10^5(N)/(m^2)`, What are the maximum and minimum pressure at a point as the wave passes through that point?

Explanation

The pressure amplitude is `p_(0) = 0 .00 N//m^(2)` . Hence, the maximum and minimum pressures at a point in the wave motion will be `(1.01 xx 10^(5) ne 0 .02)N//m^(2)` .
