A siren emitting a sound of frequency `1000 H_(Z)` moves away from you towards a cliff at a speed of `10 m//s` .
(a) What is the frequency of the sounds, you hear coming directly from the sirven ?
(b) What is the frequency of sounds you hear reflected off the cliff . Speed of sound in air is `330 m//s` ?

A siren emitting a sound of frequency 2000 Hz moves away from you towards a cliff at a speed of 8 m/s. (a) What is the frequency of the sound you hear coming directly from the siren. (b) What is the frequency of sound you hear reflected off the cliff. Speed of sound in air is 330(m)/(s) .

A siren emitting a sound of frequency 2000 Hz moves away from you towards a cliff at a speed of 8 m/s. (a) What is the frequency of the sound you hear coming directly from the siren. (b) What is the frequency of sound you hear reflected off the cliff. Speed of sound in air is 330(m)/(s) .

A siren emitting a sound of frequency 1000 H_(Z) moves away from you towards a cliff at a speed of 10 m//s . (a) What is the frequency of the sound you hear coming directly from the sirven ? (b) What is the frequency of sounds you hear reflected off the cliffb ? (c) What beat frequency would you hear ? Take the speed of sound in air as 330 m//s .

(b) What is the frequency of the sound you hear reflected off the cliff (c) What beat frequency would you hear ? Take the speed of sound in air as, 330 m/s.

A siren emitting a sound of frequency 800 Hz moves away from an observer towards a cliff at a speed of 15 ms^(-1) Then, the frequency of sound that the observer hears in the echo reflected from the cliff is

A siren emitting a sound of frequency 800 Hz moves away from an observer towards a cliff at a speed of 15 ms^-1 Then , the frequency of sound that the observer hears in the echo reflected from the cliff is:

A sound of frequency 1500 Hz is emitted by a source which moves away from an observer and moves towards a cliff at a speed of 6 ms^(-1) (a) Calculate the frequency of the sound which is coming directly from the source. (b) Compute the frequency ofsound heard by the observer reflected off the cliff. Assume the speed of sound in air is 330 ms^(-1)

A siren emitting a sound of frequency 800 Hz moves away from an observer towards a cliff at a speed of 15ms^-1 . Then the frequency of sound that the observer hears in the echo reflected from the cliff is (Take velocity of sound in air =330ms^-1 )

A siren emitting a sound of frequency 800 Hz moves away from an observer towards a cliff at a speed of 15ms^-1 . Then the frequency of sound that the observer hears in the echo reflected from the cliff is (Take velocity of sound in air =330ms^-1 )
