Jawaban:
C. 100 cm/s
Penjelasan:
1 rapatan = 8 cm
1 renggangan = 12 cm
t = 1 menit = 60 s
n = 300 gelombang
v = . . . ?
λ = 1 rapatan + 1 renggangan
= 8 + 12
= 20 cm
f = n / t
= 300 / 60
= 5 Hz
ν = λ × f
= 20 × 5
= 100 cm/s
c 100 cm/s
panjang 1 gelombang = 20 cm
banyaknya gelombang dalam menit = 300/menit
1 menit = 60 detik
jadi 20. 300/60 = 20. 5 = 100cm/s
kalau salah ya maaf
