Consider the situation shown in figure (16-E9). The wire which has a mass of 4.00 g oscillates in its second harmonic and sets the air column in the tube into vibrations in its fundamental mode. Assuming

Question

Philoid · Accepted Answer

Given:
Speed of sound in air
Length of the wire
Mass of the wire

Mass per unit length of wire is given by:

T = tension of the string

Fundamental frequency:

For second harmonic,

:

------------ (i)

On substituting the respective values in equation (i), we get:

Hence, the tension in the wire is 11.6 N.

Consider the situation shown in figure (16-E9). The wire which has a mass of 4.00 g oscillates in its second harmonic and sets the air column in the tube into vibrations in its fundamental mode. Assumingthat the speed of sound in air is 340 m s, find the tension in the wire
