What does light spread out in?
Waves
How do objects produce sound
By vibration
What is frequency
Pitch
What is the amplitude
Loudness
What is the frequency?
The distance between each wavelength
What is the aplitude
The height of each wave
The higher the frequency
The shorter the wavelength
Can sound travel through a vacuum and why
Because sound needs a material medium like air
Why does sound travel faster through solids
Because the particles are closer together than a liquid or gas meaning that the vibrations can be passed more easily
What are the three bones in the art called
Hammer anvil and stirrup
