Condition :   Excellent  
Principle :   Wave Motion  
Area of Study :  Acoustics, E & M   
Equipment :   spring, mechanical oscillator, oscillator amplifier, wave generator.

Procedure :   Attach the spring to the mechanical oscillator and stretch to between 30 and 60 cm.  Turn the wave generator from 10 to 40 hertz. as you sweep that set of frequencies you should observe the number of  standing pulses to go from 2 to about 7.
