Sound

= Sound =

﻿Speed of sound: The distance travelled during a unit of time via sound waves thus growing or propagating through an elastic medium.

Vibration & Pitch: The Vibration is measured in Hertz (Hz) basically the amount of movements to and fro per second but pitch is variable for multiple factors one of them being the size of the vibrating object or the amount of tension from the vibrating object.



Echoes: The reflection of a single sound the time delay is just the extra distance which is divided by the the speed of sound.

Doppler Effect: When the source of the sound waves is approaching closer to the observer each wave reacts more rapidly which means that the time for the object to reach the observer is reduced increasing the frequency and making the sound louder when closer to the person and that is the doppler effect.

Resonance: The tendency of a system to oscillate with a larger amplitude at some frequencies than at others.
