Abstract

The refractive index is a fundamental property of materials that describes how light propagates through a medium, enabling an understanding of optical phenomena such as refraction. This study investigates the refractive indices of water, oil, and glass using hands-on experimentation based on Snell’s Law. The researchers, who were also the participants, conducted the study as part of an independent project under the Cambridge AS Level Physics curriculum. Utilizing basic laboratory materials, including a ray box, protractor, and transparent containers, the experiment involved measuring the angles of incidence and refraction to calculate refractive indices. Each measurement was repeated three times for accuracy, and multiple angles of incidence were tested for consistency. The results showed a strong agreement between experimental and theoretical values, with refractive indices of 1.33 for water, 1.46 for oil, and 1.52 for glass, yielding percent errors of 0%, 0.68%, and 0.66%, respectively. These findings confirmed the reliability of the methodology and the validity of Snell’s Law. Minor deviations were attributed to potential sources of error, such as measurement inaccuracies and material impurities. This hands-on activity enhanced the researchers’ conceptual understanding of light behavior while promoting critical thinking, problem-solving, and independent research skills. The perspective of the students was meaningful as they enjoyed the activity. The collaborative nature of the activity was an outlet for the participants to enhance their learning. The practical approach fostered a deeper appreciation for experimental physics and demonstrated the importance of systematic data collection and analysis in scientific inquiry. By bridging theory with practice, the study highlighted the value of active learning in understanding complex physical concepts.

Abstract

Electrical resistivity is a fundamental property of materials, reflecting their ability to conduct electricity and playing a critical role in electrical engineering and material science. This experiment investigates the effect of conductor length on resistivity using a single metallic wire with lengths ranging from 10 cm to 60 cm. Resistance was measured for each wire length using a calibrated voltmeter and ammeter, and resistivity was calculated using the relation Equation 1. Experimental conditions were meticulously controlled, with consistent wire material, steady environmental temperature, and precise wire diameter and length measurements to ensure accuracy. The results demonstrate a direct relationship between wire length and resistance, validating the theoretical prediction. The calculated resistivity of the metallic wire was 2.04 x 10-8 Ω⋅m, closely aligning with the theoretical value for silver (1.59 x 10-8 Ω⋅m) and supported by the wire's shiny gray appearance. This experiment highlights the practical application of resistivity in selecting materials for electrical systems and offers a valuable hands-on approach to teaching resistivity concepts in the classroom. The findings can be integrated into physics education to enhance students' understanding of material properties, data analysis, and electrical circuit principles.

Abstract

This study explored the concept of hydrostatic pressure and its relationship with various heights of water using the PhET simulation platform. This research aims to determine the value acceleration due to gravity using the hydrostatic pressure simulation of PhET. The experiment's independent variable is the water column at various heights and the dependent variable is the pressure. The method used in this study is pure experimental wherein controlled variables like atmospheric pressure were kept constant. By systematically varying the water height above the ground, the experiment examined how pressure changes respond to these variations. A straight line of best fit was formed when pressure and height were plotted, which is consistent with the theory. This result indicated that as the height of the water column increases, the pressure increases proportionally, demonstrating the direct influence of gravity and water density on hydrostatic pressure. Also, the acceleration due to gravity was measured to be 9.82 ms-2. Therefore, the following were afforded by PhET simulation in this experiment: reliable data, convenient usage, eliminating the need for sophisticated equipment, and an intuitive interface for exploring physical phenomena. This study recommends PhET for teaching and learning processes. It engages the students and provides experiential learning to teachers and students.
