Best ResponseYou've already chosen the best response.1we can write these equations: for waves A and B: \[\Large \begin{gathered} {\lambda _A}{f_A} = {v_A} \hfill \\ \hfill \\ {\lambda _B}{f_B} = {v_B} \hfill \\ \end{gathered} \]

Best ResponseYou've already chosen the best response.1now, we have: f_A=2*f_B, and v_A=v_B, so we can write:

Best ResponseYou've already chosen the best response.1step, by step: \[\Large \begin{gathered} {\lambda _A}{f_A} = {\lambda _B}{f_B} \hfill \\ {\lambda _A}\left( {2{f_B}} \right) = {\lambda _B}{f_B} \hfill \\ 2{\lambda _A}{f_B} = {\lambda _B}{f_B} \hfill \\ \hfill \\ 2{\lambda _A} = {\lambda _B} \hfill \\ \end{gathered} \]

Best ResponseYou've already chosen the best response.0okay! and so does that mean the wavelength of A is greater than the wavelength of B? so choice B would be the solution?
