Development of an Inexpensive Spectrometer Tool with a Tracker to Investigate Light Spectrum
Abstract
Abstract One of the most fascinating areas of physics is likely optics. However, it also includes some of the phenomena that students find to be less clear-the light spectra produced by light diffraction. The experimental analysis of light spectra to evaluate radiation bodies typically requires specialized and expensive equipment that is typically out of the price range for schools. Few teachers are proficient in measuring the wavelengths of light in a spectrum. In this study, we describe a low-cost, straightforward setup that can measure light spectra accurately enough to be utilized in physics and chemistry lectures. We demonstrate how the shareware program Tracker, which is frequently used to teach mechanics, may be used to measure wavelengths with a resolution of roughly 2 nm. Several methods are also available for calibrating various setups, depending on the level of accuracy required.
Keywords optics, spectrum, experimental, wavelength.
Abstrak Optik mungkin adalah salah satu topik paling menarik dalam fisika. Namun, itu juga mengandung beberapa fenomena yang kurang dipahami oleh siswa-spektrum cahaya yang diperoleh dari difraksi cahaya. Studi eksperimental spektrum cahaya untuk mempelajari benda beradiasi biasanya membutuhkan peralatan canggih dan mahal yang biasanya tidak terjangkau oleh sekolah, dan hanya sedikit guru yang mengetahui cara mengukur panjang gelombang cahaya dalam spektrum. Dalam karya ini, kami menyajikan pengaturan yang sederhana dan murah, dengan akurasi yang cukup untuk mengukur spektrum cahaya yang akan digunakan baik di kelas fisika maupun kimia. Kami menunjukkan bagaimana Pelacak perangkat lunak freeware, yang biasa digunakan untuk mekanika pengajaran, dapat berfungsi untuk mengukur panjang gelombang dengan resolusi sekitar 2 nm. Beberapa pendekatan untuk kalibrasi pengaturan yang berbeda juga disediakan, tergantung pada tingkat akurasi yang diharapkan.
Kata kunci optik, spektrum, eksperimental, panjang gelombang.
