What are water waves classed as?
transverse and longitude
waves are a mean of transferring energy from
place to place.
frequency of a wave?
The number of waves produced each second. Measured in hertz.
Frequency x wavelength =
wave speed
20Hz - 20,000Hz figures significant?
Range of sound of human hearing
What is the relationship between speed, frequency and the wavelength of a wave?
Wave speed = frequency x wavelength
V = f x l (Greek l)
