My Notes Ask Your Teacher 5. -1 points OSColPhys2016 17.3.WA.009.Tutorial. A storm warning siren emits sound uniformly in all directions. Along a line that is drawn radially outward from the sound source (the siren) determine the positions of two points, 0.93 m apart, such that the intensity level at one point is 1.37 dB greater than the intensity level at the other. point closer to siren point farther from siren Additional Materials Reading Tutorial Submit Answer Save Progress Practice Another Version

Explanation / Answer

SL = 10 log(I / I0)

SL1 - SL2 = 10 log(I1 / I2) = 1.37

I1 / I2 = 23.44

and I r^2 = constant

I1 r^2 = I2 ( r + 0.93)^2

I1 / I2 = ( (r + 0.93)/ r)^2

r + 0.93 / r = 4.84

r = 0.242 m

closed -> 0.242 m

farther = 1.17 m
