[QUOTE="betamu, post: 6052520, member: 647527"] [h2]Homework Statement [/h2] The sound source of a ship’s sonar system operates at a frequency of 18.0 kHz. The speed of sound in water (assumed to be at a uniform 20°C) is 1482 m/s. What is the difference in frequency between the directly radiated waves and the waves reflected from a whale traveling directly toward the ship at 4.95 m/s ? The ship is at rest in the water. [h2]Homework Equations[/h2] f[SUB]ship[/SUB] = (v+v[SUB]ship[/SUB]/v+v[SUB]whale[/SUB])f[SUB]whale[/SUB] [h2]The Attempt at a Solution[/h2] To find the frequency of the reflected waves, I used the above equation with v[SUB]ship[/SUB]=0 and v[SUB]whale[/SUB]=-4.95m/s. Found the reflected frequency to be 18060.32Hz, which means a 60Hz difference. My textbook says it should be double that, 120Hz. [/QUOTE]
