BUNYI• Sumber bunyi
senar/dawai
ρ = 1250 kg/m³
L = ½ m
A = 1 mm² = 10⁻⁶ m²
F = 50 N
f₀ = __?
Frekuensi nada ke n oleh senar
fₙ = (n + 1) / (2 L) × √(F/(ρ A)
Frekuensi nada dasar
f₀ = (0 + 1) / (2 L) × √(F/(ρ A)
f₀ = 1 / (2 L) × √(F/(ρ A)
f₀ = 1 / (2 • ½) × √(50 / (1250 × 10⁻⁶)
f₀ = 1 × √40000
f₀ = 200 Hz ✔️
