ANALYSIS OF LIGHT DIFFRACTION INTERFERENCE PATTERNS IN YOUNG'S DOUBLE SLIT EXPERIMENT
Keywords:
Interference, , double slit experiment, wave properties of lightAbstract
Young's double-slit experiment is a classic and fundamental
demonstration in physics that strongly supports the wave nature of light through
the phenomenon of interference. The study aims to deeply analyze the formation
of diffraction and interference patterns of light that arise due to the path
differences between two coherent light sources. The experiment uses a simple yet
effective setup involving a monochromatic light source, two narrow slits placed
close together, and a screen placed at a certain distance to capture the resulting
interference pattern. Several variables are analyzed in the study, including the
wavelength of the light used,the distance between two gaps and the distance from
one gap to anotherThe experimental results confirm the occurrence of
constructive and destructive interference, resulting in the formation of stripes
moving from bright to dark in the layer. These stripes arise due to the phase
difference between overlapping light waves, and their spacing and clarity are
affected by the physical parameters of the setup. The analysis shows that the
spacing between the stripes increases with longer wavelengths and decreases with
wider slit spacing. In addition, the cohesion of the light source plays an important
role in producing a clear and stable interference pattern. This experiment not only
serves as a concrete verification of the theoretical wave principle in physics, but
also has broader implications in modern optical technologies such as diffraction
gratings, holography, and quantum mechanics. This experiment is also relevant
for educational purposes because it provides an experiential learning opportunity
for students to understand the behavior of light and wave interactions. Therefore,
this study is expected to be a useful reference in supporting the teaching and
learning of wave optics, especially in demonstrating the dual nature of light and
its applications in real-world phenomena.
