Question

Please solve question no. 8

Answer 1

Answer:

Velocity = n lemda

lemda - wavelength

lemda = 341/341 = 1m

Resonance at Heights

First Resonance

H1 = lemda/4

H1 = 0.25 = 25cm

Second Resonance

H2 = 3Lemda /4

H2 = 3× 25 = 75cm

Third Resonance is impossible

H3 = 5lemda/4

H3 = 5 × 25 = 125cm

Tube length is 100cm

Only 2 Height Resonance Takes place
