Music and instruments

Question 1

natural frequency

Answer 1

All materials have a natural frequency at which they will vibrate when a force is applied

Ex. when you strike a piece of wood or metal it makes a sound

Question 2

Resonace

Answer 2

By creating vibrations that constructively interfere with the natural frequencies of the material, we can create a sound that can be heard

This is called resonance - a wave that vibrates very close to the natural frequencies of  another material which interferes constructively with the natural frequencies of the material

This is how musical instruments work

A vibration is applied to the material of the instrument which resonates at a specific  frequency to create an audible sound

Question 3
