The sound source of a ship’s sonar system operates at afrequency of 18.0 kHz. The speed of sound in water (assumed to beat a uniform 20°C) is 1482 m/s. (a) What is the wavelength of thewaves emitted by the source? (b) What is the difference in frequencybetween the directly radiated waves and the waves reflected from awhale traveling directly toward the ship at 4.95 m/s ? The ship is atrest in the water.
