“…The slit distance is investigated by spectral analysis with Tracker can be more precise (Pratidhina et al, 2020). Educators and scientist use Tracker to teach and study various topics such as vector object falling in liquid and air (Sirisathitkul et al 2013), projectile motion (Yusuf, 2016), mechanical energy (Bryan, 2010), damped harmonic oscillation (Poonyawatpornkul & Wattanakasiwich, 2013), torsion (Eadkhong et al, 2012), and impulse (Ayop, 2017).…”

This research was conducted by making a rectangular slit using a razor blade as a narrow gap in the Fraunhofer diffraction experiment. The intensity distribution measurement on the resulting diffraction pattern uses a voltage divider circuit. This circuit takes advantage of the nature of the LDR, which changes resistance when exposed to light. Experiments show that a diffraction pattern screen when a 560 nm coherent light passes through a narrow rectangular slit made of razor cut. We measured the narrow gap using a tracker application with the resulting gap size (0.3564 x 0.4677) mm. The ratio of the intensity distribution of the x-axis bright pattern on the Fraunhofer diffraction by a rectangular slit with slit size height x width = (0.4677 x 0.3564) mm from b = -5p to 5p (maximum 4, maximum 3, maximum 2, maximum 1, central maximum, maximum 1, maximum 2, maximum 3, maximum 4) is 0.000873; 0.000763; 0.005395; 0.020583; 1; 0.039658; 0.008088; 0.002554; 0.001218. The ratio of the intensity distribution of the y-axis bright pattern on the Fraunhofer diffraction by a rectangular slit with slit size height x width = (0.4677 x 0.3564) mm from g = -5p to 5p (maximum 4, maximum 3, maximum 2, maximum 1, central maximum, maximum 1, maximum 2, maximum 3, maximum 4) is 0.001890; 0.001469; 0.002447; 0.040516; 1; 0.037141; 0.006482; 0.001690; 0.000440. This study indicates that diffraction experiments and the measurement of the diffraction pattern’s intensity can be carried out with simple materials and equipment and can be used in the correct experiment.

Exploring Fraunhofer diffraction through Tracker and spreadsheet: An alternative lab activity for distance learning

2020

View full text Add to dashboard Cite

In this paper, we present an alternative for physics laboratory activity related to Fraunhofer diffraction in distance learning. The activity utilizes a demonstration video from MIT Open CourseWare, Tracker software, and spreadsheet. An online demonstration video is used because it is the most accessible resource during undesirable conditions such as COVID 19 pandemic. In the activity, students can explore diffractions phenomena with multiple slits. The effect of slit spacing and slit numbers to the intensity of light is investigated trough spectral analysis with Tracker. The investigation is followed by a discussion through the mathematical approach and visualization with spreadsheets. It will enrich students with a theoretical explanation of the observation. This distance learning activity allows students to develop their science process skills, mathematical and computational thinking skills, and conceptual understanding of Fraunhofer diffraction.

“…Tracker includes features such as object tracking with position, velocity, and acceleration overlays and graphs, calibration points and line profiles for analysis of spectra and interference patterns [1]. Some studies have explored the potential of Tracker for pedagogical learning tools [2][3][4][5]. Poonyawatpornkul and Wattanakasiwich [3] use Tracker to analyze damped harmonic oscillation; Rodrigues and Simeão Carvalho [6] use Tracker to teach optical phenomena; Wee, Tan, Leong, and Tan [5] integrate Tracker in physics class when discussing free-fall motion.…”

In this study, we demonstrate an interesting relationship between simple harmonic motion and uniform circular motion trough a simple experiment. The experiment requires a low cost-easily found materials and free software, Tracker. To represent uniform circular motion, we use a tape that is stick on a fan moving with the constant angular speed. Meanwhile, spring and pendulum motion are used to represent simple harmonic motion. Through Video Tracker analysis, we have shown that the positions (x and y coordinates) of an object undergoes uniform circular motion fit to the sinusoidal function of time, as same as shown in simple harmonic motion. This simple experiment can be used in high school physics course to lead students in developing a conceptual understanding of uniform circular motion with a less mathematical approach.
