1. A source moving with a speed 37 m/s, emits a sound wave with a frequency f = 377 Hz. Determine the frequency detected by a stationary observer if the speed of sound is v = 343 m/s and the source is moving towards the observer. 2.A stationary source, emits a sound wave with a frequency f = 428 Hz. Determine the frequency detected by an observer moving towards the source with a speed v = 43 m/s, if the...

Homework 7.2 The sound frequency a listener hear will be shifted to a higher value if the listener is moving towards a stationary source or the sound source is moving towards the stationary listener. However, the shifts are not the same for the same speeds in these two cases. Derive the relationship of the two speeds (speed of the listener and the speed of the sound) for the same frequency shift assuming the sound speed relative to the medium is...
When the source of a wave and an observer move either towards or away from each...
When the source of a wave and an observer move either towards or away from each other the observed frequency of the wave will be different from the frequency at which the wave is emitted. For example, if you are standing by the side of the road and a police car with a siren passes by, the frequency of the sound you hear will be higher when the car is moving towards you and lower when it is moving away...

Let the speed of sound be 340 m/s. A source emits a sound of 327 Hz. It is moving towards the right with a speed of 39 m/s and approaching an observer who is moving towards the left with a speed of 36 m/s. What is the frequency heard by the observer? Enter an integer.

When viewed by an observer on the Earth, light from a distant galaxy is Doppler shifted to the red such that the ratio of the unshifted frequency to the observed frequency is 1.6. What is the galaxy's speed relative to the Earth?
