Reference no: EM13510949

Two submarines are underwater and approaching each other head-on. Sub A has a speed of 17 m/s and sub B has a speed of 8 m/s. Sub A sends out a 1590 Hz sonar wave that travels at a speed of 1522 m/s.

(a) What is the frequency of the sound detected by sub B?

(b) Part of the sonar wave is reflected from B and returns to A. What frequency does A detect for this reflected wave?
