Description

Wave Motion Apparatus “Powell’s Pattern” with rotating scale

The IEC version of ‘Powell’s Wave Motion Apparatus’ is a moulded and quietly running system, whereas other designs are noisy and rattily. The system demonstrates both longitudinal and transverse wave motion and the 0-360deg. scale at the handle allows study of the sine wave action relative to the angle rotated by the cams.

Demonstrate Transverse Wave Motion

The handle, which is at one end of the machine, is rotated to cause a series of cams to rotate. These cams cause a set of 16 vertical rods to rise and fall sequentially as the cams rotate beneath them. Their motion follows that of a Sine Wave since their vertical motion is caused by the circular rotary motion of each cam. The transverse motion, which is clearly visible by observing the tips of the rods, is a demonstration of the creation of Sine Waves as perhaps created in a ripple tank or in a vibrating guitar string.

Demonstrate Longitudinal Wave Motion

A set of 8 rods at one end of the machine protrude horizontally through a guide loop and move in a longitudinal motion relative to one another. This longitudinal motion is also Sine Wave. This longitudinal motion is a demonstration of the compression and extension of the coils of a spring when set into a longitudinal vibration or in the radiation of radio energy from an antenna into the atmosphere.
