[21a-P2-7] Young's Interference Experiment Using a LED Light (Ⅳ)
Keywords:Young's expeiment,interference
We have developed the teaching aid for Young's Interference Experiment where we faithfully use a lamp,
single-slit and double-slit as is seen in the physics textbooks. We used a highly-sensitive color CCD camera to record the interference pattern to detect the higher-order bright lines. As a result, we observed the 17-th bright lines and the Fraunhofer diffraction pattern. Futhermore, we clearly confirmed the perod between the bright lines is varied according to the wavelength of the incident light.
