抄録 We faithfully reproduced Young’s historical interference experiment using a developed teaching aid trial product consisting of a single slit, a double slit, and an incoherent light source. A high-luminance white light-emitting diode (LED) was used as the light source, and a color charge coupled device (CCD) camera was used for recording the interference fringes to make the product easy to handle. By using monochromatic filters and a high-sensitivity CCD camera, we clearly observed the interference fringes and the Fraunhofer diffraction pattern. The measured periods of bright stripes in the fringe agreed very well with the calculated periods. We then checked the coherence condition by shortening the distance between the single and the double slit. We found that the distance should be more than 25 mm under our experimental conditions to observe clear interference fringes. Finally, we investigated the validity of the approximation in calculating the periods of bright stripes, which is usually recommended in physics textbooks. The measured distance between the 0th and 30th bright stripe did not agree well with the calculated one when the approximation was used. Therefore, the approximation is valid when we measure the position below the 30th bright stripe in the interference fringe. The physical characteristics investigated here are useful for performing physics experiments in high schools and universities.
