Two train whistles A and B each have a frequency of 220 Hz. A is stationary and B is moving toward the right (away from A) at a speed of `35 m//s` . A listener between the two trains is moving towards the right with a speed of `15 m//s` . No wind is blowing.
What is frequency from A as heard by the listener

Two train whistles A and B each have a frequency of 220 Hz. A is stationary and B is moving toward the right (away from A) at a speed of 35 m//s . A listener between the two trains is moving towards the right with a speed of 15 m//s . No wind is blowing. What is the frequency from B as heard by the listener?

Two train whistles A and B each have a frequency of 220 Hz. A is stationary and B is moving toward the right (away from A) at a speed of 35 m//s . A listener between the two trains is moving towards the right with a speed of 15 m//s . No wind is blowing. What is the beat frequency detected by the listener. The speed of sound = 330 m//s

Two tuning forks A and B having a frequency of 500 Hz each are placed with B to the right of A. An observer in between the forks in moving towards B with a speed of 25 m/s. The speed of sound is 345 m/s and the wind speed is 5 m/s from A to B. Calculate the difference in the two frequencies heard by observer.

The speed of sound is 345 m/s and the wind speed is 5 m/s from A to B. Calculate the difference in the two frequencies heard by observer.

A source whistling a sound of frequency 450 Hz moves towards a stationary listener with a speed of 33 m/s. If velocity of sound is 333 m/s, then find frequency of sound heard by this listener.

Two tuning forks A and B lying on opposite sides of observer 'O' and of natural frequency 80 Hz move with velocity 10 m//s relative to stationary observer O . Fork A moves away from the observer while the fork B moves towards him. A wind with a speed 10 m//s is blowing in the direction of motion of fork A . Find the beat frequency measured by the observer in Hz. [Take speed of sound in air as 340 m//s ].
