P₅ = 80 cm = 0,8 m
f = 10 Hz
v = ...........?
Penyelesaian :
* Mencari panjang gelombang
Pn = (2n + 1)¼λ
P₅ = 0,8 m
0,8 = (2(4) + 1)¼λ
3,2 = (2(4) + 1)λ
3,2 = (8 + 1)λ
3,2 = 9λ
λ = 3,2/9
λ = 0,355 m
* Mencari cepat rambat
v = λ x f
v = 0,355 x 10
v = 3,55 m/s
Jadi, cepat rambar gelombangnya adalah 3,55 m/s
x = (2.4 +1) 1/4 lamda
0,8 = 9/4 lamda
lamda = 3,2 / 9
lamda = 0,35
v = lamda . f
v = 0,35 . 10
v=3,5 m/s
maaf ya lamda nya gk pke smbl soal nya aku gk tau
