Question

The speed of sound is measured by a resonance tube at the room temperature once by filling the tube with water and then with glycerine as v₁ and v₂ . Which of the following relations is/are true in this context?

(a)  v₁ = 2v₂

(b)  v₁ > v₂

(c)  v₁ < v₂

(d) v₁ and v₂ does not depend on the nature of the liquid taken in the tube.

Answer 1

Correct option  (d) v₁ and v₂ does not depend on the nature of the liquid taken in the tube. 

Explanation:

The velocity depends on the length of the resonating air column, not on the nature of the liquid.
