sound Flashcards
The top of a wave is called
The peak
The peak of a wave to the line is called
The amplitude
From one side of a wave to another is called
The wavelength
The bottom of a wave is called
The trough
What is compression
The part of a longitudinal sound wave in which the particles are close together and there is a high pressure
What is rarefaction
The part of a longitudinal wave where the particles are spread the furthest as there is a reduction of pressure
How does sound move
When the particles hit each other and pass on the vibrations
Does sound travel faster through air or water
Water. Because the partciles are closer together. This allows them to bounce off each other and pass on the vibrations
Instruments and pitch
The pitch of instruments can increase by reducing the length of the air column.
