A braking train emits a very loud, high-pitched sound.Explain whether the amplitude, frequency and wavelength of the sound waves are relatively high or low.

A sound wave that is low-pitched and loud would have what characteristics?Group of answer choiceshigh frequency, low amplitudeScratchlow frequency, low amplitudeScratchhigh frequency, large amplitudeScratchlow frequency, large amplitude

A train is moving past a crossing where cars are waiting for it to pass. While waiting, the driver of the lead car becomes sleepy and rests his head on the steering wheel, unintentionally activating the car's horn. A passenger in the back of the train hears the horn's sound at a frequency of 435 Hz and a passenger in the front hears it at 413 Hz. Find the train's speed and the horn's frequency, assuming the sound travels along the tracks. Take the speed of sound to be 343 m/s.HINT(a)the train's speed (in m/s) m/s(b)the horn's frequency (in Hz) Hz

As a train starts from rest and then accelerates down the track, coming toward me faster and faster, the speed of the sound waves coming toward me will be:Select one:a.some constant speed faster than the normal speed of sound in air.b.equal to the normal speed of sound in air.c.faster and faster.d.slower than the normal speed of sound in air.

Which wave property determines a) loudness, b) Pitch?Q12. Why are the ceilings of concert halls curved?Q13. How is ultrasound used for cleaning?Q14. Sound is produced due to a vibratory motion, then why a vibrating pendulum doesnot produce sound?Q15. A sound produces 20 crests and 20 troughs in 0.4 sec. Find the frequency of the wave.Q16. Why sound waves are called mechanical waves?

Find the speed of the sound wave? The time from the beginning to the end of the wave train is 1 second. Wavelength of the wave is 3 cm.
