Asound wave of frequency 167 hz has an intensity of 4.89 w/m2. what is the amplitude of the air oscillations caused by this wave? (take the speed of sound to be 343 m/s, and the density of air to be 1.21 kg/m2.) jem lem number 1.56 units to the tolerance is +/-2%

the amplitude on the wave in the air is: 1.46*10^-4 m-

Explanation: In order to calculate the amplitude of the wave in air we have to use the formule of intesity of the wave given by:

I=1/2*(ρ*v*ω^2*A^2)  where ρ,v and ω, are the density of air, speed of sound and angular frequency of the wave, respectively. A is the amplitude of the wave.

Reorganising the above formule,  we can obtain that A is equal to:

replacing the data  A=1.46*10^-4 m

are there answer choices to this question? this seems like a question where you have options to choose from.
