When an engine bumps into a string of coupled railroad cars on a track, it creates a compression wave. This wave travels through the cars and causes them to move as the energy is transferred from one car to the next until the wave dissipates.

Is an engine bumping into a string of coupled railroad cars on a track producing transverse or compressional waves?

An engine bumping into a string of coupled railroad cars on a track produces both compression and transverse waives. The engine bumping into the cars creates compressional waves down the string of cars. These waves are taken up by the spring action of the Janney couplers. The law of inertia can cause transverse waves in the coupling motion that can force railroad cars off the track. Think of it this way. If all cars in a cut weight about the same, as one car bumps into the other most of the force is passed down the string of cars. If a empty car pushes into a loaded car too fast the empty car may not have the force to start the loaded car moving. All the force that the empty car has has to go somewhere. The only direction it can go is up or to the side derailing the empty car. That's why there are restrictions on how fast cars can be coupled together. The spring action in the couplers in railroad terms is called slack.


Tone produced by one vibration of a string?

The tone produced by one vibration of a string is called a fundamental frequency. This fundamental frequency is the lowest frequency at which the string will vibrate, and it determines the pitch of the note that is produced.


Can a string instrument play a note lower than the note produced from its lowest string?

No.


How does a guitar string's physical change produce sound?

The sound is produced by the vibration of the string.


Why does tightening a guitar string raise the pitch of the string when its played?

It increases the frequency of the sound waves produced by by the plucked string.


Why does tightening a guitar string raise the pitch of the string when it is played?

It increases the frequency of the sound waves produced by by the plucked string.


Which form of energy produced when a guitar string vibrates?

What is the string instrument played with the fingertips?

Pizzicato is produced on a string instrument by plucking the string with the finger.


Why does tightening a guitar string raise the pitch of the string when it's played?

It increases the frequency of the sound waves produced by by the plucked string.


What type of wave can be produced on a stretched string?

A transverse wave can be produced on a stretched string. In this type of wave, the motion of the particles of the medium is perpendicular to the direction of the wave propagation.


How does sound travel through a string instrument?

it is produced by the string vibrating on the instrument when you strum it.


Plucking a guitar string is a physical change however the process produces sound?

Plucking a guitar string is a physical change because the string's shape and composition remain the same. The sound is produced due to the vibrations created when the string is plucked, which travel through the air as sound waves.
