A source and an observer are moving towards each other with a speed equal to `v/2` where v is the speed of sound. The source is emitting sound of frequency n . The frequency heard by the observer will be

A source and a listener are both moving towards each other with speed v//10 , where v is the speed of sound. If the frequency of the note emitted by the source is f , the frequency heard by the listener would be nearly

A source and listener are both moving towards each other with a speed v/10 where v is the speed of sound. If the frequency of the note emitted by the source is f, what will be the frequency heard by the listener?

A source of sound and an observer are approaching each other with the same speed which is equal to (1)/(10) times the speed of sound. The apparent change in the frequency of the source is

A source of sound and an observer are approaching each other with the same speed, which is equal to (1/10) times the speed of sound. The apparent relative change in frequency of source is
