Ripple tank (Ceiling projection type) RT-Y2

C15-4006-W0

【Product Description】

Ripple tank for the observation of basic wave behavior of water in its shallow tank by projection onto the ceiling.

【Overall Advantages to Users】

  • This ripple tank originaly invented by high school teacher, received the Minister of Education, Culture, Sports, Science and Technology Prize awarded by Toray Scientific Foundation in 2007. (https://www.toray-sf.or.jp/en/index.html).
  • This device enables a ceiling projection of ripples by placing a stroboscopic light source of a high brightness LED under the water tank.
  • All students in the classroom can observe the behavior of waves at the same time thanks to projection on the ceiling of the classroom.

【To all users】

  • Controling indivually two vibrators enables the observation of the constructive interference and destructive interference depending on wave’s phase difference.
  • Doppler effect can be demonstrated by moving circular waves produced by a point spherical ball of the wave source.
  • Huygens’ construction can be demonstrated by multi circular waves produced by a multi spot paddle at the wave source.

【To teachers】

  • This ripple tank enables demonstration of wave properties such as wave refraction, reflection, diffraction, and interference of a plane wave, a circular wave.
