Indirectly asked everything......Classical Mechanics Level 5
Find the \(beat~frequency~detected~by~O~in~Hz\).The source of sound and observer move with velocities of \(20~m/s~and~40~m/s\) respectively in the same line. The frequency of the source emitting the sound is \(1000~ Hz\).A wall is placed in front of the observer.
Details and Assumption
Take velocity of sound in air \(340~m/s\)
