Question

the excess pressure in a longitudinal wave is given by​

Answer 1

Explanation:

wave pressure can be max or min when displacement is zero depending on the number of particles at a point.

equation of wave s=s

o

sin(kx−ωt)

and pressure p=p

o

cos(kx−wt)

Answer 2

po*Cos(kx-wt) is the excess pressure in a longitudinal wave.

Explanation:

Wave pressure can be maximum or minimum when displacement is zero depending on the number of particles at the point.

Equation of wave s=so*Sin(kx-wt) {w = omega}

Equation of pressure p=po*Cos(kx-wt)
