Abstract

Automation of three slit interference experiments has been carried out. The light interference is an interesting phenomenon to observe. The observation of the three-slit interference pattern uses a light sensor that is connected to the computer through the interface. Light intensity data will be directly recorded into the computer and displayed in the form of graphs of the light intensity versus time. To measure the pattern of the formed dark light, the light sensor is placed on a linear drive system. This drive system will move the sensor to the left or right to record the intensity of the pattern of dark light. The purposes of this study are: 1) designing an automatic experiment to observe three slit interference patterns and 2) measuring the wavelength of the light source, He-Ne laser, used in the experiment. From the experiment, we find that the wavelength of He-Ne laser is  nm.

Abstract

This study reports on the use of smartphone camera and power point application to analyze the kinematic motion experiment. This method is intended to make a better understanding of students concept using the tools that are commonly owned by students. The experiments performed in this study were one-dimensional (1-D) represented by falling motion and two-dimensional (2-D) using parabolic motion. In evaluating the experimental results, the obtained data were compared to the theoretical values that were calculated using analytical approach. The use of this method shows great measurement results in showing dependency of falling motion to gravitational acceleration and proofing the constant velocity at projectile motion on its horizontal plane in which it is comparable to the theoretical value. The video analyzation method also can be used as an alternative solution to the established software, even better when the higher resolution camera and frame rate was used. Noting that the tools used in the experiment were common tools around, thus, this can be used as a replacement for the advance tools.
