Wzory:

$\lambda = v\cdot T \ - \ dlugosc \ fali\\\\v = \frac{\lambda}{T} \ - \ predkosc\\\\T = \frac{\lambda}{v} \ - \ okres\\\\f = \frac{1}{T} \ - \ czestotliwosc$

Obliczenia:

$\lambda = v\cdot T = 10\frac{m}{s}\cdot8 \ s = 80 \ m\\\\\lambda = v\cdot T = 160\frac{m}{s}\cdot0,4 \ s = 64 \ m\\\\T = \frac{\lambda}{v}= \frac{120 \ m}{30\frac{m}{s}} = 4 \ s\\\\T = \frac{1}{f} = \frac{1}{5 \ Hz} = 0,2 \ s\\\\T = \frac{\lambda}{v} = \frac{8 \ m}{400\frac{m}{s}} = 0,02 \ s$

$f = \frac{1}{T} = \frac{1}{20 \ s} = 0,05 \ Hz\\\\f = \frac{1}{8 \ s} =0,125 \ Hz\\\\f = \frac{1}{T} = \frac{1}{4 \ s} = 0,25 \ Hz\\\\f = \frac{1}{T} = \frac{1}{0,4 \ s} = 2,5 \ Hz\\\\f = \frac{1}{T} = \frac{1}{0,02 \ s} = 50 \ Hz\\\\v = \frac{\lambda}{T} = \frac{600 \ m}{20 \ s} = 30\frac{m}{s}\\\\v = \frac{\lambda}{T} = \frac{100 \ m}{0,2\ s} = 500\frac{m}{s}$
