You live along the flight path of planes coming in for a landing at the airport. The intensity of sound waves from a plane's engines is 4.0 x 107 W/m2 when the plane is at an altitude of 10000 m. A. What is the power of the sound waves emitted by the engines (assuming the sound travels equally in all directions)? P = W B. What is the intensity of the sound waves emitted by the engines when the plane is at an elevation of 100 m? I = W/m²
