Waves

Waves

1. Amplitude, Wavelength, Frequency & Speed

   • waves are disturbances that are caused by a vibrating source
   • They carry and transfer energy in the direction the wave travels, they do not transfer matter
   • AMplitude is distance from the rest position to the crest/troogh
   • Wavelength is the length of a full cycle (crest to crest)
   • Frequency is the number of complete waves /s

2. Transverse / Longitudinal

   • TRANSVERSE WAVES THE VIBRATIONS ARE AT 90 DEGREES TO THE DIRECTION OF TRAVEL OF THE WAVE(vribrations are up and down)
   • LONGITUDINAL WAVES ARE VIBRATIONS ALONG THE SAME DIRECTION AS THE WAVE IS TRAVELLING

3. Wavespeed = frequency x wavelength
