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 20o C) is 1482 m/s. (a) What is the wavelength of the waves emitted by the source? (b) 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.

Solution 75P (a).In problem first we have to calculate the frequency of wavelength,generally the wavelength can be calculated by velocity of source's sound divided by source's frequency. = v sfs. First we have to note down given that gives an idea how to solve and which formula we have to use Given data: The sound source of a ship’s sonar system operates at a frequency of f =18.s kHz. The speed of sound in water is v =14s2 m/s. Whale traveling directly toward the ship at v =4w95 m/s Then = v /f s s = 1482 m/s/18 × 10 Hz3 = 0.0824 m =...
