When both source and observer approach each other with a speed a equal to the half the speed of sound, then determine the percentage change in frequency of sound as detected by the listener.

When both source and listener approach each other with a velocity equal to half the velocity of sound, the change in frequency of the sound as detected by the listener is (frequency of sound = n)

When both source and listener approach each other with a velocity equal to half the velocity of sound, the change in frequency of the sound as detected by the listener is

When both source and listener approach each other with a velocity equal to half the velocity of sound, the change in frequency of the sound as detected by the listener is

When both source and listener approach each other with a velocity equal to half the velocity of sound,the change in frequency of the sound as detected by listener 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

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 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 producing a sound of frequency 90 Hz is approaching a stationary listener with a speed equal to (1/10) of the speed of sound. What will be the frequency heard by the listener?
