PURPOSE: Ordinary wave experiment equipment is provided to educate general properties of ordinary waves to students and to maximize a learning effect of the students by arousing interest and curiosity of the students. CONSTITUTION: General properties of ordinary waves are learned by grasping the principles of an ordinary wave generator. Ordinary wave experiment equipment arouses interest and curiosity of students by visualizing the ordinary waves having abstract concepts. A learning effect regard to science of the students is maximized through observation. The learning effect is increased by directly showing the ordinary waves. The ordinary waves are formed by using optical fiber. A waveform at a desired cycle is obtained by turning on an LED in a specific frequency by using rotation of a censor and the optical fiber. |
