This work aims to introduce a low-cost experimental set up using an Arduino board for studying the magnetic induction concept. We use a Hall Effect sensor to detect the magnetic fields inside a long solenoid applied the DC current. The results revealed that for the DC current varied from 20-160 mA, the Arduino sensor processed the magnetic fields in a range of 0.77 - 5.27 mT. Collected data...

For various experiments to investigate quantum effects, matter-wave diffraction is an apparent example. Particle diffractions have been measured even at the large molecular level, such as the C$_{60}$ molecules. In order to describe the matter-wave diffraction of C$_{60}$ beam, we assume the initial wave functions behind a grating in form of the Fourier series with a Gaussian distribution...

A group of physicists from Mexico developed a standard test in vector conceptions without any physics related context called “Test of Understanding of Vectors (TUV)”. This test was first conducted as open-ended questions which later on was re-designed as a 20-item multiple-choice test. Since physics is a subject that involves quantities like vectors, and students’ understanding of concepts in...

Sound speed in the air can be measured from resonance phenomena in an open-open tube. In a typical undergraduate laboratory, sound is generated with a specific frequency, and lengths associated with resonance are recorded. Subsequently, those data can be used to determine the sound speed. Instead of using a specialized apparatus, this work demonstrates a method to measure sound speed using...

Schlieren photography is a technique used to capture air movement based on difference in fluid density. Air with higher temperature has lower density than surrounding air with lower temperature, leading to different values of refractive index. This work aimed to determine optimized conditions for schlieren photography to capture air movements in several situations. Schlieren photography was...

Pencil leads can be used to draw resistors, which are low-cost and easy to obtain. Not all types of pencils are considered good for pencil resistors because pencil lead is made up of graphite, an allotrope of carbon. Resistance of graphite varies with the grades used during manufacturing, as such we aimed to review and test several types of pencils would be best for developing DC pencil...

Teaching and learning astronomy is not effectively in class event in the University level. Because the concept of astronomy is abstract and complicate for students. Many of student teachers have difficulty of how to create their lesson to help students learn astronomy. Because of they are not confident in concepts of astronomy. Especially in the concept of celestial sphere, the concept is very...

Linear least square is a common method to fit two dimensional data set with linear relation. In non-linear case we need to do some linearization before fitting. Parameters can be extracted from the fitted line and used to predict new dependent variable values at new independent variable points. In this report we investigate the uncertainty introduced to a non-linear model prediction from...
