삼차원 조화진동 이해를 위한 교육자료 개발 = A teaching material for understanding three dimensional harmonic vibrations

다국어 초록 (Multilingual Abstract)

We propose a teaching material for helping students understand phenomena related to the three dimensional harmonic vibration. The simple harmonic motion of a particle attached springs on a horizontal frictionless plane (a two dimensional plane) can be visualized by so called Lissajous figures. Extending it by using the track of laser beam on vibrating screen after two reflections from the two mirrors vibrating in the two perpendicular directions to the vibration direction of the screen, we made a teaching material to visualize phenomena related to the simple harmonic motion in the three dimensional space.
