- Standing waves.
Bulgaria Design and perform and experiment, in which standing waves are used to measure how the sound speed depends on the air temperature.
Croatia With right frequency played from an emitter, small balls can be levitated by standing waves between a speaker and a reflector. Investigate the phenomenon and parameters of the system.
Georgia Consider a thin plate whose center starts to vibrate. If sand is placed on the plate, it will distribute in a complex pattern. Investigate how pattern depends on the relevant parameters.
Greece-Alliance Find the relationship between the length of a rope oscillating with a stable frequency and its linear mass density and tension.
Greece-Fryganiotis Find the relationship between the length of a rope oscillating with a stable frequency and its linear mass density and tension.
Iran-Innovative Researchers Why are standing waves produce? Measuring the volume of the sound. Effective parameter such as frequency and wave length. Standing waves definition. Waves are a vibration or oscillation that transmits energies. The main characteristics of a wave.
Iran-Valeh What is wave? What are the general classification of wave types? Explanation of the main characteristics of a wave. Standing waves definition. Different experiments about standing waves. Test equipment in experimental design.
Kazakhstan-Bobek We study an ordinary tube with cork dust in it and drive 660 Hz into this pipe.
Kazakhstan-RFMS Study of various parameters affecting the occurrence and shape of Faraday waves.
New Zealand A plastic ruler is fastened to an oscillator at its center and oscillated at different frequencies, at certain frequencies nodes are formed. Investigate relevant parameters that affect the position of the nodes.
Romania-LIMITLESS Observation and study of the presence of standing waves with a technical setup applied in a household environment.
Romania-NITRO Investigate the physics of standing waves and standing waves on guitar strings. Can you play harmonics on guitar strings? Which standing wave patterns you can produce on a guitar string by playing harmonics?
Russia-Unartificial Intelligence Standing Waves in Musical Bottles.
