Longitudional Waves

Transverse Mode Of Vibration

A sonameter wire vibrates with three nodes and two antinodes, the corresponding mode of vibration is ……… .

A steel rod of length 100 cm is clamped at the middle. The frequency of the fundamental mode for the longitudinal vibrations of the rod is (Speed of sound in steel = 5 km s^(-1) )

The frequency of fundamental mode of vibration of an air column enclosed in a closed end pipe is 250 Hz. If its length is 33 cm , find the velocity of sound in air.

In the fundamental mode of vibration on a stretched string, the number of antinodes are

Draw the fundamental modes of vibration of stationary waves in : An open pipe.

Draw the fundamental modes of vibration of stationary waves in : Closed pipe.

The frequency of fundamental mode of vibration of a stretched string fixed at both the ends is 25 Hz. If the string is made to vibrate with 7 nodes , what is the frequency of vibration ? If the length of string is 3 m , what is the frequency of the 4th harmonic ?
