Abstract

In this project, a tool that can explain phenomena involving the photoelectric effect at laboratory scales is being developed. The purpose of this tool is to help users understand that the photoelectric effect, which causes electrons to move from a source of a negative voltage to a source of positive voltage, is not affected by light intensity but rather by a light source's frequency and wavelength. A photodiode is employed in the creation of this device as a light sensor, and when exposed to light, it moves electrons from the cathode to the anode, causing an electric current to flow. The voltage is delivered to the cathode, which is where the electrons leave, to calculate the stopping voltage. A graph showing the connection between the ADC value and the sensor output voltage is produced from the ongoing data gathering. Our results show that each color spectrum has a distinct voltage supplied to the photodiode leg (cathode). Additionally, the output voltage measured for each distinct wavelength was decreased the lower the photodiode's light intensity was.

Abstract

Effective learning can be achieved by utilizing practical teaching aids that can challenge students to understand the material. This needs to be done to increase students' lack of learning motivation, as it will hurt learning achievement. Each student has a variety of learning styles, such as visual, audio, and kinesthetic. Therefore, teachers should try to create innovation by developing teaching aids in the form of a Pascal pressure model that can be implemented in learning experiments. The purpose of making this demonstration equipment is so students can understand the concept of Pascal pressure more concretely and in-depth, compared to relying on pictures as a visual tool. Apart from that, this innovation can also increase student motivation so that learning becomes more real and not just imagination and so that student learning outcomes can increase. The research method involves identifying old materials that can be used, designing creative and educational teaching aids, as well as testing the effectiveness of teaching aids in supporting science learning. The research results show that using used materials in natural science teaching aids can reduce negative environmental impacts by reducing waste and consuming new resources. The teaching aids developed can also facilitate understanding of science concepts visually and interactively. The trial of this teaching aid showed a positive response from students toward a more interesting and sustainable learning method.

Abstract

The most interesting problem to be discussed in electrical physics is one-way electric circuits. In this work, the researchers constructed an experimental setup for determining the time constant of DC resistors and capacitors using the open-source Arduino UNO hardware platform. Arduino UNO was a signal generator for data collection systems and a simple signal visualization instrument. Experiments were carried out using an analog oscilloscope combined with theoretical calculations. The results show that, on a spreadsheet, the data processing and fitting of the curves for the six Resistor and Capacitor test sets yielded values determined by the component tolerances. The researchers believe that the design of this equipment and software demonstrates the recommended suitability, making it flexible for use in teaching and learning in laboratory contexts.

Abstract

Color is a certain spectrum contained in a perfect light (white). The purpose of this study is 1). Can determine the cause of the color of the object (what causes a different object than the other color) 2). Can observe the color that occurs when two or more colors are mixed. The benefit in order to inform readers about what actually causes the color of the object and what if two or more colors are mixed. Mixing colors for color RGB, the colors Red to Green produce colors orange, blue color to produce a color Sian Green, Red color with blue produce magenta, and Red, Green with Blue produces white color. For CMY color mixing, the colors Cyan with yellow produce green color, magenta with yellow produces red color, the color Cyan by Magenta produces blue, and the colors Cyan, Magenta produces yellow Gray (Brown). Color objects can be invisible to the eye because of the reflection of the color of the object illuminated by light.

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.DOI: http://dx.doi.org/10.23960/jpmipa/v24i1.pp28-38
