e, however, that the curve cc and the origin 0 are bothtraveling to the right at velocity v so that the abscissa of themoving origin 0 with respect to the stationary origin 0 is vtas shown. Then the abscissa x of any point on the curve cc IS X ELECTRIC OSCILLATIONS AND ELECTRIC WAVES. 197 = x + vt… … Fig. 135. Similarly it may be shown that y = f(x + vt) (3) is the equation of a curve traveling to the left at velocity v withrespect to a stationary origin. The two equations (2) and (3) satisfy one of the most importantof the differential equations of physics, namely, the differentialequation of…
