Two persons are playing shehnai made of the same material. Shehnai I is 1.5 times the length of shehnai II. Let f₀^ (I) and f₀^ (I I) be the fundamental frequencies of shehnai I and shehnai II respectively. Then,

Options

  1. A3 f₀^ (I I) =f₀^ (I)
  2. B3 f₀^ (I I) =2 f₀^ (I)
  3. C2 f₀^ (I I) =3 f₀^ (I)
  4. Df₀^ (I I) =3 f₀^ (I)

Correct answer

C. 2 f₀^ (I I) =3 f₀^ (I)
