What is the difference between noise and sound?
Sound is quieter than noise
Noise is unwanted sound
Noise is wanted sound
Noise only travels through air
The wavelength is
the time is takes to complete one cycle/ oscillation
the number of waves per second
the distance between two crests
the maximum height of the wave from its resting position
Amplitude is
