Explanation:
Given A cylindrical tube of length 120 cm and with a tuning fork of frequency 330 if it is formed by water than to get resonance minimum length of water column is b is equal to 330 metre per second
- We know that ν = nλ
- So λ = ν / n
- = 330 / 330
- = 1 m
- So first resonance will be
- L1 = λ / 4 = 1/4 = 25 cm
- So second resonance will be
- L 2 = 3λ / 4 = 3/4 = 75 cm
- Third resonance will be
- L3 = 5λ/ 4 = 5/4 = 125 cm
- Now maximum height of water will be 120 – 75
- = 45 cm

Answer:
f=(2n−1)v/4l
l=(2n−1)v/4f=(2n−1)×330/4×330=(2n−1)/4
l=14m,34m=25cm,75cm.
∴ Minimum height of water column
=120-75=45cm
