t = 10 menit = 10 x 60 = 600 s
n = 12.000
λ = 1,2 m
Ditanyakan : v ?
Dijawab :
frekuensi :
f = n/t
= 12.000/600
= 20 Hz
Cepat gelombang :
v = λ x f
= 1,2 x 20
= 2,4 m/s
n = 12000
t = 10 menit
= 600 s
λ = 1,2 m
ditanya =
v = ...
dijawab =
f = n / t
= 12000 / 600 s
= 20 Hz
v = λ . f
= 1,2 m . 20 Hz
= 24 m/s
