Standing Wave in a Spring - 5th
A spring is attached to a speaker at one end and a support at the other end. A sine wave generator drives the vibrations of the speaker. The up and down vibrations of the speaker introduces longitudinal waves within the spring. The frequency is adjusted until a standing wave pattern is established. The nodal positions within the spring are observed clearly since these are stationary coils of no disturbance. The anti-nodal positions are characterized by coils that vibrate back and forth at high frequency. These positions are blurred due to the rapid motion of the coils.
