Two train whistles, A and B , each have a
frequency of 396 Hz . A is stationary and B is
moving toward the right (away from A ) at a speed of 35.0
m/s . A listener is between the two whistles and is moving toward
the right with a speed of 15.0 m/s . (See (Figure 1) .)

4. In one of the original Doppler experiments, a tuba was played on a train at a speed of 60 km/h, at a constant frequency of 75 Hz, while a second identical tuba played the same note on the platiorm at the railway station. Assume the observer is standing still on the platiorm on a day when the outside air temperature is 20° C a. What is the effect that is observed regardless of any sound from the tuba at...

Doppler Effect You are waiting at a train station when an approaching express train sounds its 400 Hz horn, warning everyone to stand back from the platform as it passes. If you perceive the frequency of the horn to be 425 Hz as the train approaches, how fast must the train be moving towards you? You may assume the speed of sound is 343 m/s.

Thinking and Inquiry Two train whistles, A and B each have a frequency of 392Hz. A is at rest while B is moving at 35m/s [right]. A railway worker moving at 15 m/s[left] is between the two trains. Air temp is 293 K. 14. a) What is the frequency heard by the railway worker from Train A? (3) b) What is the frequency heard by the railway worker by train B? (3) c) What is the beat frequency heard by...

Tuning fork 1 Tuning fork 2 Bob 9.0 m - 3.0m - Two identical tuning forks are positioned 9.0 m apart, and emit sound equally in all directions. Alex is standing exactly halfway between the tuning forks, and Bob is standing 3.0 m to the right of the rightmost tuning fork. Alex hears an intensity of one tuning fork of 55 dB playing at 300 Hz. 1. How much power is emitted as sound by one tuning fork? 2. When...

Example 18.7 The Mistuned Piano Strings Two identical piano strings of length 0.775 m are each tuned exactly to 400 Hz. The tension in one of the strings is then increased by 1.0%. If they are now struck, what is the beat frequency between the fundamentals of the two strings? SOLVE IT Conceptualize As the tension in one of the strings is changed, its fundamental frequency changes. Therefore, when both strings are played, they will have different frequencies and beats...
