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)`.

To solve the problem, we will break it down into two parts as specified in the question. ### Part (a): Frequency of the sound you hear coming directly from the siren 1. **Identify the given values:** - Frequency of the siren (f₀) = 2000 Hz - Speed of sound in air (v) = 330 m/s - Speed of the source (vₛ) = 8 m/s (since the siren is moving away from the observer) ...

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 sound of frequency 800 Hz is going away from a static listener with a speed of 30 m/s. Frequency of the sound to be heard by the listener is ( Take velocity of sound as 300 m/s )

An observer is standing 500 m away from a vertical hill. Starting between the observer and the hill, a police van sounding a siren of frequency 1000 Hz moves towards the hill with a uniform speed. If the frequency of the sound heard directly from the siren is 970 Hz, the frequency of the sound heard after reflection from the hill (in Hz) is about,(velocity of sound = 330ms^-1

A source of sound of frequency 500 Hz is moving towards an observer with velocity 30 m/s . The speed of sound is 330 m/s . the frequency heard by the observer will be

Consider the vehicle emitting sound wave of frequency 700 Hz moving towards an observer at a speed 22 m s^(-1) . Assuming the observer to be at rest, and speed of sound to be 330 m s^(-1) , the frequency of sound as measured by the observer is

A source and a detector move away from each other, each with a speed of 10 m/s with respect to ground with no wind. If the detector detects a frequency 1650 Hz of the sound coming from the source, what is the original frequency of the source? (speed of sound = 340 m/s

A car emitting sound of frequency 500 Hz speeds towards a fixed wall at 4(m)/(s) . An observer in the car hears both the source frequency as well as the frequency of sound reflected from the wall. If he hears 10 beats per second between the two sounds, the velocity of sound in air will be

A van is moving with a speed of 3ms^(-1) towards a large wall. A person standing on the line of motion of the van observes the van to be moving away from him. The horm of the van is now blown. The frequency of the sound produced by the horn is 600 Hz. what is (i) The frequency of sound heard by the person for the sound produced directly by the horn? (ii) The freuquency of sound reflected by the wall. (iii) The baat frequency heard by the driver. the speed of sound in air is 330ms^(-1)?

A train moving at a speed of 220ms^-1 towards a stationary object emits a sound of frequency 1000 Hz. Some of the sound reaching the object gets reflected back to the train as echo. The frequency of the echo as detected by the driver of the train is (speed of sound in air is 330ms^(-1) )
