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

To solve the problem step by step, we will break it down into two parts: (a) finding the frequency, wavelength, and speed of the sound wave, and (b) determining the maximum and minimum pressure at a point as the wave passes through that point.

### Part (a): Finding Frequency, Wavelength, and Speed

1. **Identify the parameters from the wave equation**:
The given wave equation is:
\[
\Delta p = (0.02) \sin[(3000)t - (9.0)x]
