Va = Vb

√Fa/μa = √Fb/μb

√Fa.la/mₐ = √Fb.lb/mb

√Fa.la/ρVa = √Fb.lb./ρ.Vb

√Fa.la/ρ.Aa.la = √Fb.lb./ρ.Ab.lb

√Fa/Aa = √Fb/Ab

Fa/Aa = Fb/Ab

Aa/Ab = Fa/Fb

Aa/Ab =  5/25

Aa/Ab =  1/5

(π/4.Da²) / (π/4.Db²) = 1/5

Da²/Db² = 1/5

Da/Db = √(1/5) = 0,45

Ada 6 perut dan ujung-ujung senar merupakan simpul

3λ = 2

λ = 2/3 m

f = v/λ = √F/μ / (2/3)

f = 3/2. √30/(2.10⁻³)

f = 3/2. 10²√3/2

f = 183,7 Hz
