A source that is continuously emitting sound at constant frequency, starts moving away from the detector with initial speed 4 m/s, along the line joining them. The acceleration a of the source is opposite to velocity having value 1 m/ s 2 . If the motion starts at t = 0 s then frequency as recorded by the detector from t = 0 to t = 8s
Text Solution
Verified by ExpertsThe correct answer is:
D
At t = 4 sec. source turns direction of motion and starts moving towards detector.
Thus for whole duration f increases.
