Abstract

This research aims to investigate/determine the value of the laser wavelength produced by He-Ne lasers and Diode lasers using the concept of diffraction at a single slit. The gaps used consist of three types of gaps which have gaps with a width of 0.12 mm, 0.24 mm, and 0.48 mm. Experimental results show that the wavelength of He-Ne laser light ranges from 640 nm to 646 nm. Meanwhile, the wavelength of He-Ne laser light ranges from 640 nm to 686.67 nm. Based on the results obtained, it can be concluded that it is proven that the wavelength calculated using the single slit diffraction method is in the range of values for lasers that emit red light.

Abstract

The constant volume type gas thermometer has an important role as a learning medium that can help students understand the concept of absolute temperature more easily and concretely. Considering that this tool is difficult to find in the market, it is necessary to make an effort to make and develop the tool. The purpose of this development research is to produce a product in the form of a fixed volume type gas thermometer that is better than the existing one. The research method used is research development that includes research and data collection, planning, developing product drafts, developing learning materials, learning processes, and evaluation instruments, initial field trials, field trials, refining product field test results, perfecting final products and implementation.
