OSCILLATING MOTION
Wave machine. Transverse and longitudinal waves HG0097
An aid to demonstrate the phenomenon of transverse and longitudinal waves. Very useful in observation and exploration of such issues connected with a wave as its length, frequency, amplitude, reflection and period. The machine consists of a shaft with a crank at its end. Rotation of the shaft sets the vertical rods with white spots in motion. Additionally, 8 rods bent at the same given angle to help observe how both types of waves are formed. • size: 50 x 12 x 30 cm; weight 0.85 kg; material: plastic
