- Homework Statement
- Here we have subtracted the phase 4pi from S2 than S1. Why
- Relevant Equations
- y=a cos (wt)
See fig(a), S1Q=7lambda
S2Q=9lambda
I think since source S2 is lagging behind. So, we should add the phase 4pi instead of subtracting it from the cosine function. Wouldn't subtracting the phase further delay the wave more.
