Consider Figure 1. Estimate the phase di®erence between the waves y(x; t) and g(x; t)(adsbygoogle = window.adsbygoogle || []).push({});

at time t0. Select the result closest to your estimate.

A. 2.09 radians B. 0.333 C. 0.167

D. 1.045 radians E. 0.5 m F. None of these

Solution: 2.09 radians

I know the answer comes from (Distance/Time)2pi = Phase Difference(angle)

And thus Distance = 0.5m(between the same point on both waves in fig 1a) and time has to be 1.5s. The problem is, I dont know where te 1.5 comes from?? From the diagram is anyone able to assist???
