Abstract

Wave–particle dualism is a fundamental concept that has shaped physics since the early twentieth century and remains central to modern physics research. This study aims to examine the development of wave–particle dualism through three key phenomena: black-body radiation, the photoelectric effect, and Compton scattering. The method employed is a systematic literature review of 10 peer-reviewed journal articles published between 2018 and 2024, focusing on theoretical perspectives, experimental evidence, and conceptual implications. The results indicate that research on black-body radiation has progressed from the development of high-precision radiation sources toward the control of atomic energy shifts and light polarization. Studies on the photoelectric effect reveal its dual role as both an effective educational tool through simple, low-cost experiments and a platform for advanced investigations of electron momentum distribution. Meanwhile, research on Compton scattering spans practical applications such as radiation detector calibration and theoretical modeling of photon–electron interactions in extreme quantum fields. Overall, this study demonstrates that wave–particle dualism is not merely a historical concept but an evolving framework that continues to inform theoretical development, experimental validation, and technological innovation. The findings have implications for physics education, experimental design, and future research on quantum phenomena by highlighting the interconnected nature of foundational quantum effects.

Abstract

The Twin Paradox stands as one of the most challenging thought experiments in Einstein's special theory of relativity, seemingly revealing an internal contradiction within the theory itself. This paradox illustrates the scenario of twin siblings where one travels through space at relativistic speeds while the other remains on Earth. A naive analysis from both perspectives yields contradictory conclusions: each twin predicts the other would be younger. This apparent contradiction forms the core of the paradox. The paradox can be completely resolved within the framework of special relativity without needing to invoke general relativity. This research uses a library research method by collecting data from various relevant sources that support the twin paradox in the concept of time expansion. Experimental verification through the Hafele-Keating experiment with atomic clocks and observations of atmospheric muon decay confirms the theoretical predictions.
