Abstract

Previous research only used one type of color, namely red. Then, researchers developed it by using three types of colors. In this research, we want to analyze the wavelengths produced by laser pointers of different colors, identify the distance between the grid and the screen, identify the distance between the central bright spot, and analyze the relationship between the lattice constant and the distance from the center of the light to the next light. The research method used was direct observation in the optics laboratory. The laser pointer was used as a monochromatic light source to produce a diffraction grating. Laser light sources have many colors, but we only use three colors, namely red, green and violet (purple). This experiment uses three different grating constants (????), namely a 100 slit/mm grating, a 300 slit/mm grating and a 600 slit/mm grating as well as the distance between the grating and the screen (????) (which are also different, namely 15 cm, 20 cm and 30 cm respectively). each grating constant. Based on the data that has been obtained, for red, violet and green laser light, for grating constants of 100 slits/mm, 300 slits/mm and 600 slits/mm produce the same wavelength and approaching the wavelength indicated on the laser, as well as the wavelength range of visible light.

Abstract

This research is motivated by the process of making a simple resonant pipe tool in organa pipe practicum. The purpose of writing this research is to analyze the effect of frequency on the speed of propagation of sound using paralon and prove the experiment on the speed of propagation of sound. This research is done by experiment, where the pipe is inserted in a container in the form of a bucket filled with water, and the audio generator application is placed on the pipe until it produces the biggest sound with a certain tone which is done by raising the position of the pipe. The results of this study are organa pipe practicum using simple tools carried out by trials and obtained data on the speed of propagation generated at frequencies of 1400 Hz, 2000 Hz and 2600 Hz sequentially by 350 m/s, 360 m/s and 364 m/s. The research gives the result that f ~ v and the results show that the sound propagation speed data is close to 340 m/s. So it can be concluded that the frequency with the speed of propagation of sound is directly proportional through a simple organa pipe experiment, and the resulting propagation speed of both frequencies of 1400 Hz, 2000 Hz, and 2600 Hz around the original propagation speed of 340 m/s. Therefore, this organa pipe props can be called accurate and can be easier to use for students.

Abstract

This research aims to analyze the comparison of standing wave results between waves on a guitar string and waves on a cord. The study is conducted through two separate experiments, focusing on understanding the relationship between wave velocity and tension on the string, understanding the relationship between wave propagation speed and mass per unit length on the string, and analyzing the comparison of standing wave results. The first experiment is focused on observing the changes that occur as the tension value on the string increases. Meanwhile, the second experiment is designed to observe the tight binding of the string’s mass and the propagation speed of sound waves. Standing waves, also known as standing waves, emerge as a result of interference between two waves with the same frequency and amplitude but different propagation directions. The amplitude peak occurs at the node, while the antinode indicates the minimum amplitude. Essentially, waves are generated from a string attached to a vibrator.
