Jaka jest prędkość fali o długości 0,4m jeśli jej częstotliwość wynosi 60Hz?

Witaj dane L=0,4m, f=60Hz szukane v L = v*T....../jak s = v*t/......f = 1/T.......T = 1/f L = v/f v = f*L = 60Hz*0,4m = 24m/s..........1 Hz = 1/s
...................pozdrawiam

Lambda = 0,4 m f = 60 Hz = 60 1/s V = ? V = lambda /T T = 1/f T = 1/60 s
dane L=0,4m, f=60Hz
szukane v
L = v*T....../jak s = v*t/......f = 1/T.......T = 1/f
L = v/f
v = f*L = 60Hz*0,4m = 24m/s..........1 Hz = 1/s
...................pozdrawiam
f = 60 Hz = 60 1/s
V = ?
V = lambda /T
T = 1/f
T = 1/60 s
V = 0,4 m/1/60 s
V = 24 m/s
