CanMousePlate said:A man hammers on a steel railway track. If you hear the sound through the track 5.0 seconds sooner than through the air, how far away is the man?
*Steel - 5960m/s
*Air - 346 m/s
The question is simple but i can't get it
Also please explain how to do a question like this in the answer.
Sound waves are produced when an object vibrates, causing the air particles around it to also vibrate. These vibrations travel through the air as sound waves.
The pitch of a sound is determined by its frequency, which is the number of vibrations per second. A high pitch sound has a higher frequency and more vibrations per second, while a low pitch sound has a lower frequency and fewer vibrations per second.
Sound waves can travel through different mediums such as air, water, and solids. The speed of sound varies depending on the medium, with sound traveling faster through solids than air. This is because the particles in a solid are closer together, allowing sound waves to travel more quickly through them.
A transverse sound wave moves perpendicular to the direction of the wave, while a longitudinal sound wave moves in the same direction as the wave. Most sound waves are longitudinal, with the particles vibrating back and forth in the same direction that the sound wave is traveling.
When two sound waves meet, they can interfere with each other. Depending on the phase of the two waves, they can either amplify or cancel each other out. This is known as constructive and destructive interference. This phenomenon is used in noise-cancelling technology, where sound waves are manipulated to cancel out unwanted noise.
