Öğretmen adaylarının duran dalga kavramına yönelik kavramsal anlamaları

“…The standing wave happens on a wire, a plate, a bar, air column, sound or electromagnetic waves; it can take place in most systems which have a vibration. In other words, standing wave is a concept that should be mentioned during the teaching of waves (Serway & Beichner, 1997). However, when literature on waves was examined, there were limited number of studies on waves.…”

“…Because a simple harmonic motion takes place on each point of the string, the string vibrates horizontally, and during this vibration, stagnancy is preserved on the nodal points of the wave pattern. In other words, the energy density of the standing wave varies according to frequency and amplitude (Serway & Beichner, 1997). Standing wave, which can be defined as having peak and bottom points always observed in the same dimension, can be said to be a same-frequency wave stemming from the same source or two same-frequency waves stemming from the same source.…”

“…Each particle of the environment is exposed to maximum motion from the balance state at antinode points; however, each particle with an opposing phase can go to a balanced state with a simple harmonic motion. As a result, motion for particles in all values of certain intervals is again zero (Serway & Beichner, 1997). When the standing wave concept is examined in daily life, it can be said that a standing wave is observed in bows, water, sound, and electromagnetic waves.…”

“…As such, new notes occur, and compositions are made. In other words, the frequency of a string instrument may vary when the length of the string or its F tightening is altered (Serway & Beichner, 1997). In wind instruments, certain holes are likewise made to enable free vibration of air.…”

“…Thus, the resonance frequency can be continuously changed with the air inside, and the standing wave can be formed within the instruments (Tipler & Mosca, 2003). Finally, when we put two loudspeakers across each other, the loudspeakers that propagate sound at the same frequency and density can be said to emit two identical waves in opposing directions and that a standing wave pattern can be obtained with the superposition of these two waves (Serway & Beichner, 1997).…”
