Sound velocity measurement and acoustic levitation experiment

  SEK-8107

 

 

 

DETAILS

The instrument is composed by acoustic levitation experimental device and signal source. It can operate on acoustic levitation experiment and also can repeat traditional measuring velocity of sound experimental context

Experimental contents

1. Master resonance interference method, phase-comparison method and time-difference method to measure the velocity of sound in different medium.

2. Master using acoustic levitation phenomenon to measure the velocity of sound.

Features

a) Use ultrasonic to suspend the object in the air medium.

b) Observing the resonance and sine distribution in the air medium can be a demonstrative experiment for acoustic levitation. And also it can be used for measuring ultrasonic wavelength by acoustic levitation and the experimental context by repeating traditional measuring the velocity of sound experiment.

Instrument: Sound velocity measuring combination instrument Unit 1 set,  dedicated signal source Unit 1 set,  dual trace oscilloscope  Unit 1 set.

Average  λ =9.156mm,Experimental value:Ve = f x λ = 37.855 x 103 x 9.156 x 10-3 = 346.60m/s.

Relative error: E=|Ve-Vt|/Vt x 100% = |346.60-343.37|/343.37 x 100% = 0.94%

b) Measuring the velocity of sound wave in the air by phase method.
