An ideal gas havi

Given:

An ideal gas having density 1.7 × 10^–3 g cm^–3 = 1.7 kg m^–3 at a pressure 1.5 × 10⁵ Pa is filled in a Kundt tube.

When the gas is resonated at a frequency of 3.0 kHz, nodes are formed at a separation of 6.0 cm.

the node separation is given by which is 6.0cm. Therefore,

the frequency of the sound (f) is 3kHz

thus velocity of sound =

again,

where P is the pressure and is the density of the gas.

Thus
