Workshop on Stationaty waves

Dive into the world of stationary waves at the Diana Giczi Jurisich Miklós High School in KŐSZEG. Explore how waves are produced in elastic media and how energy is maintained to sustain waves. Learn about wave reflection, refraction, diffraction, and interference, as well as the characteristics of stationary waves compared to travelling waves. Discover examples of stationary waves in different mediums such as an elastic spring and thin films of soapy water. Experience three-dimensional waves, such as sound in a tube or on a mercury drop, through practical experiments.

  1. Physics Teachers’ Conference Workshop on Stationaty waves Diana Giczi Jurisich Miklós High School KŐSZEG

  2. Waves can be produced in an elastic medium (practically in all media) Energy is lost quickly as vibration travels in the medium. We have to give the energy continuously to produce a wave for a long time

  3. Waves Reflect refract diffract interfere

  4. Waves reflect at the boundary • On fixed end • in oppositephase On free end in the samephase

  5. Stationary waves Travelling and reflecting waves interfere one end free both ends fixed

  6. Examples: In an elastic „spring” Different overtones To produce more nodes bigger frequency is needed, more and more difficult

  7. On an elastic surface: E.g. thin film of soapy water Three dimensional e.g. sound in a tube:

  8. On mercury drop As the experiment shows
