Abstract

The invention relates to a two-slit interference and single slit diffraction experimental instrument which comprises a horizontal plate. The two-slit interference and single slit diffraction experimental instrument is characterized in that a supporting rod is fixedly arranged on one side of the middle of a first supporting column, a laser is horizontally and fixedly arranged at the top end of thesupporting rod, a first sleeve is horizontally and fixedly arranged at the top end of the first supporting column, the laser and the first sleeve are located on a same horizontal line, a second sleeveis arranged out of the end, far away from the laser, of the first sleeve in a sleeving manner, a gap head is arranged at the end, far away from the first sleeve, of the second sleeve in a sleeving manner, and sliding blocks are fixedly arranged at the bottoms of a second supporting column and a third supporting column. By arranging the adjusting supporting columns and a horizontal tester, the horizontal degree of the horizontal plate is adjusted conveniently, so that the experimental result is more accurate. By arranging a brightness adjustor, the brightness of a light source sent by the laser can be adjusted. By arranging a first fastening screw, the gap head is replaced and mounted conveniently. By arranging the sliding blocks, the positions of a light screen and the gap head are adjusted conveniently.

Description

technical field [0001] The invention relates to the technical field of a teaching demonstration instrument, in particular to a double-slit interference single-slit diffraction experiment instrument. Background technique [0002] Double-slit interference and single-slit diffraction is an important knowledge point in physics, and it is also a relatively basic physical experiment in the process of physics teaching. The discussion of its light intensity distribution and spacing is an important and difficult point. Qualitative observation is mainly used, that is, the laser is used as the light source to directly irradiate the double-slit device, and then the human eye is used to observe on the observation screen. The existing experimental equipment is not easy to promote in classroom teaching, and it is inconvenient to demonstrate, which affects the experimental effect. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provide...
