A source of sound and a detector are placed at the same place on ground. At t = 0, the source S is projected towards reflector with velocity V0 in vertically upward direction and reflector starts moving down with constant velocity V0. At t = 0, the vertical separation the reflector and source is H(>v202g) . The speed of sound in air is v(>>v0). Take f0 as the frequency of sound waves emitted by source. Based on above information answer the following questions.
Actual frequency emitted by source doesn't upon the velocity of source but frequency heard due to relative motion between the observer and the source.
