Velocity of sound in air by Resonance tube

Equipment:

• Two Glass tubes with diameter 4 cm and length 60 cm.
• Function generator 1MHz.
• Loud speaker.
• Two metallic stand.
• Two metallic base.
• Rubber connection.
• Metallic Multi clamp for the tubes.
• Cables.

Description

• Sound waves travel through medium by one of two methods:
1- longitudinal waves : in which the particles of the medium displacement in the same direction of the wave as compression and rarefaction as sound in air.
2- transverse waves : in which the particles of the medium displacement perpendicular to the direction of the wave .
• This setup used for determining velocity of sound in air by using audio signal generator and loudspeaker.
