Question

State the purpose of obtaining resonating length in the experiment.

Answer 1

Hey buddy,
You didn't mention which type of experiment. From the question I assume you are talking about resonance column experiment.

◆ Answer -
Resonating velocity is obtained for calculating velocity of sound in air at room temperature.


◆ Experiment-
We use resonance column experiment to calculate velocity of sound in air at room temperature.

Velocity is calculated by formula -
v = 2f(l2-l1)

Where,
f = frequency of sound
l1 = first resonating length
l2 = second resonating length

Hope it helps...
