The variation in the pressure of helium gas, measured from its equilibrium value, is given by ΔP = 2.9 × 10−5 cos (6.20x − 3 000
nadya68 [22]

Answer:

The wavelength of this wave is 1.01 meters.

Explanation:

The variation in the pressure of helium gas, measured from its equilibrium value, is given by :

\Delta P=2.9\times 10^{-5}\ cos(6.2x-3000t)..............(1)

The general equation is given by :

\Delat P=P_o\ cos(kx-\omega t)...........(2)

On comparing equation (1) and (2) :

k=6.2

Since, k=\dfrac{2\pi}{\lambda}

\dfrac{2\pi}{\lambda}=6.2

\lambda=1.01\ m

So, the wavelength of this wave is 1.01 meters. Hence, this is the required solution.
