Graphs of Transverse & Longitudinal Waves Graphs of Transverse Waves There are two common graphs transverse waves; Displacement against distance Displacement against time These are: Similar?bec...
Transverse Waves Transverse Waves A transverse wave is one where the particles oscillate?perpendicular?to the direction of the Propagation of the wave Direction of energy transfer Transverse waves ...
Longitudinal Waves Longitudinal Waves A longitudinal wave is one where the particles oscillate?parallel?to the; Propagation of the wave Direction of energy transfer Longitudinal waves show areas of...
The Wave Equation The Wave Equation This equation links wave speed, frequency and wavelength Where: v?= velocity of the wave (m s–1) f?= frequency of the wave (Hz) λ?= wavelength (m) The wav...
Properties of Waves Waves are generated by?oscillating sources These oscillations travel?away?from the source Oscillations can propagate through a?medium?(e.g. air, water) or in a?vac...
Area Under a Force-Extension Graph For a material which obeys Hooke's law, the elastic strain energy,?Eel?can be determined by finding the area under the force-extension graph Since this are...
