Waves

Wave frequency can be seen as the
number of complete of complete waves
passing a fixed point in one second.

Use the formula triangle to check the three versions of this
equation

Speed = wavelength x frequency


 wavelength =   speed
                     frequency      frequency  = speed
                                                          wavelength

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.
