    Three light waves combine at a point find resultant amplitude and phase angle

    Well I already did the way I suggested and the answer I got was : ER = 2Eo sin (\omegat)cos(\pi/3) taking cos(\pi/3) = 1/2 then equals ER = Eosin( \omega t) . Is this right?

    Three light waves combine at a point find resultant amplitude and phase angle

    Homework Statement Three light waves combine at a point where their electric field components are E1 = Eo sin \omegat E2 = Eo sin (\omegat - 2\pi/3) E3 = Eo sin (\omegat + \pi/3) Find the resultant amplitude of the electric field ER at that point and it's phase angle\beta Write...
