Experiments to arouse students' interests in physical optics
Author(s): Kazue Ishikawa

Paper Abstract

Two optical experiments, optical sensitometry and spectrograph, are prepared for sophomores majoring in physics. The purpose of the first experiment is to examine the sensitivities and contrasts of photographic films. Students learn a correct development processing method for scientific photography through the experiment. The purpose of the second experiment is to take spectrograms of various light sources. Students obtain knowledge and experimental techniques for spectroscopy using a spectrograph with logarithmic slit. It is proposed to perform a preliminary experiment. Students will be familiar with experimental operation. Thus the actual experiment can be done more smoothly by the knowledge of the preliminary experiments. Moreover, students' interest in understanding the actual experiment has increased. In addition, taking pictures by a pin-hole camera has opened students' minds to the world of physics optics.
