Question

There are two organ pipes of the same length and the same material but of different radii. When they are emitting fundamental notes.

पर्याय

• broader pipe gives note of smaller frequency.

• both the pipes give notes of the same frequency.

• narrower pipe gives note of smaller frequency.

• either of thern gives note of smaller or larger frequency depending on the wavelength of the wave.

Answer 1

broader pipe gives note of smaller frequency.

Explanation:

`f = v/λ = v/(l + e)`

f = `v/(4(L + e))`   ...(e = 0.3 d ≈ 0.6 r)

Broader pipe has more value of e therefore, it gives note of smaller frequency.
