1-141-0665 Seismic Wave Model (PS Kun)

Students can enjoy and easily understand the difference between the arrival times of the P-wave and the S-wave.

• This is an experimental instrument that can visually understand the difference between the speeds of longitudinal and transverse waves by using a domino.
• The same number of dominos for longitudinal and transverse waves were arranged, but the difference in arrival time was reproduced by the difference in the way of falling.
• The LED lamp lights up from the moment it arrives, so you can also see it from the students behind the classroom.
• Emergency Earthquake Early Warnings use the difference between the arrival times of P-waves (longitudinal waves) and S-waves (transverse waves) to provide forecasts and alarms.
• Domino starts simultaneously with red and blue by the simultaneous start mechanism and one-touch operation.
