Waves
Wave frequency can be seen as the
number of complete of complete waves
passing a fixed point in one second.
Frequency is measured in Hertz (Hz)
1 Hertz is 1 wave per second
1 kilohertz (KHz) is 1000 Hz and is 1000
waves per second
1 megahertz is 1000000 Hertz (Mhz)
1 gigahertz is1000000000 Hertz (Ghz) The wave equation Wave speed = wavelength x frequency
        a          =         b          x    c
Use the formula triangle to check the three versions of this
equation

Speed = wavelength x frequency


 wavelength =   speed
                     frequency      frequency  = speed

Types of wave
Transverse
wave
This is where The
particle movement
producing the wave
Is at right angles to the
direction of the wave
motion
Light (electromagnetic
Spectrum) waves,
water waves and
secondary (S) waves
in earthquakes are
transverse waves.
Longitudinal
wave
This is where the
particle movement
is parallel (in the same
direction) as the wave
motion. These are
called pressure waves.
Sound and primary
waves (P) in
earthquakes are
longitudinal waves.
