Two loudspeakers M and N are located 20m apart and emit sound at frequencies 118 Hz and 121 Hz, respectively. A car in initially at a point P, 1800 m away from the midpoint Q of the line MN and moves towards Q constantly at 60 km/h along the perpendicular bisector of MN. It crosses Q and eventually reaches a point R, 1800 m away from Q.

Let v(t) represent the beat frequency measured by a person sitting in the car at time t. Let v

Let v(t) represent the beat frequency measured by a person sitting in the car at time t. Let v

_{P}, v_{Q}and v_{R}be the beat frequencies measured at locations P, Q and R respectively. The speed of sound in air is 330 ms^{$$-$$1}. Which of the following statement(s) is (are) true regarding the sound heard by the person?2
