Prosze o pomoc na szybko potrzebuje z tylko zadanie 8.16!!

[latex]Dane:\f_1 = 20[Hz]\f_2 = 20[kHz] = 20000[Hz]\v = 340 [ frac{m}{s} ] \\Szukane :\lambda = ? \\Rozwiazanie :\v = fcdot lambda / :f \lambda = frac{v}{f} \\lambda _1 = frac{340[ frac{m}{s}] }{20[Hz]} =17[m]\\lambda _2 = frac{340[ frac{m}{s}] }{20000[Hz]} =0,017[m][/latex]

[latex]Dane: \ \ f_{1}=20Hz \ \ f_{2}=20kHz=20000Hz \ \ v=340 frac{m}{s} \ \ lambda_{1}=? \ \ lambda_{2}=? \ \ lambda_{1}= frac{v}{f_{1}} \ \ lambda_{1}= frac{340 frac{m}{s} }{20Hz} =17[ frac{m}{s}*s]=17m \ \ lambda_{2}=frac{v}{f_{2}} \ \ lambda_{2}= frac{340 frac{m}{s} }{20000Hz} =0,017m[/latex]
