The time average of S over one or more cycles is called the wave intensity, I, which gives the very important result that the intensity of a light wave is proportional to the square of the amplitude of the electric or magnetic fields: 22 max max ...
Transverse waves on a string - Harvard University
scholar.harvard.eduIn section 4.1 we derive the wave equation for transverse waves on a string. This equation will take exactly the same form as the wave equation we derived for the spring/mass system in Section 2.4, with the only difierence being the change of a few letters. In Section 4.2 we discuss the re°ection and transmission of a wave from a boundary.
