The intensity of a sound wave at a fixed distance from aspeaker vibrating at 1.0kHz is 0.60W/m^2. a)determine the intensity that results if the frequency isincreased to 2.50 kHz while a constant displacement amplitude ismaintained It would seem to me you would need to know the displacementamplitude The intensity of a sound wave at a fixed distance from aspeaker vibrating at 1.0kHz is 0.60W/m^2. a)determine the intensity that results if the frequency isincreased to 2.50 kHz while a constant displacement amplitude ismaintained It would seem to me you would need to know the displacementamplitude
Explanation / Answer
from the theory we have the equation I = (1 / 2) 2s2max v (a) at f = 2500 Hz the frequency is increased by a factor2.50 so the intensityincreases by (2.50)2 = 6.25 (b) 0..60 W / m2
