“…In the final chapter of the learning area for the QP, Einstein's photoelectric theory is discussed by noting Einstein's success in explaining the photoelectric effect's characteristics by introducing the photon energy concept. His photoelectric effect equation is derived following the Principle of Conservation of energy and discusses the work function of metal and the threshold frequency of light in emitting photoelectrons with several problem-solving questions related to the equations [28]. The curriculum also highlights the photoelectric effect applications for QP concept applications, including a photocell circuit [29] at the end of the chapter.…”

As a relatively new subject in the physics curriculum of Malaysian secondary schools, quantum physics (QP) raises questions about its relevance to students and the best approach for teaching it. This paper aims to analyze the content of the QP curriculum to provide students with a meaningful learning experience and expose them to the nature of science (NOS). To accomplish this, the Malaysian standard curriculum document known as Dokumen Standard Kurikulum dan Pentaksiran (DSKP) and the textbook were analyzed through integrative review. Frameworks and perspectives identified by Stadermann and co-workers on the common trust of the QP curriculum in 15 different countries were used as a benchmark for this analysis. It is found that the QP curriculum in Malaysia focuses on the fundamental principle of understanding the quantum energy of light and its interaction with matter. However, it is also found that there are specific NOS aspects that can be highlighted to help students develop their scientific literacy. These might include emphasizing the philosophy of complementarity in explaining the wave-particle duality principle, the ultraviolet catastrophe, and the contradiction of classical physics interpretation with QP. It is suggested that the QP curriculum be improved by including these and other relevant examples to be on par with other countries. Overall, this analysis provides insight into the relevance and content of QP in Malaysian secondary schools. The proposed changes may help improve students’ learning experience and provide a more comprehensive understanding of the NOS.

“…As already mentioned, underwater, practically, ultraviolet radiation is absent. Therefore, using UV LED as light emitter and a UV LED, used as APD, as receiver allows to have a system that is not very sensitive to environment light; an LED can detect radiation with a wavelength slightly shorter than or equal to that emitted (Internal photoelectric effect) [56], [57], [78].…”

For military divers, having a robust, secure, and undetectable wireless communication system available is a fundamental element. Wireless intercoms using acoustic waves are currently used. These systems, even if reliable, have the defect of being easily identifiable and detectable. Visible light can pass through sea water. Therefore, light can be used to develop short-range wireless communication systems. To realize secure close-range underwater wireless communication, the Underwater Optical Wireless Communication (UOWC) can be a valid alternative to acoustic wireless communication. UOWC is not a new idea, but the problem of the presence of sunlight and the possibility of using near-ultraviolet radiation (near-UV) has not been adequately addressed in the literature yet. In military applications, the possibility of using invisible optical radiation can be of great interest. In this paper, a feasibility study is carried out to demonstrate that UOWC can be performed using near-ultraviolet radiation. The proposed system can be useful for wireless voice communications between military divers as well as amateur divers.

“…In this paper, GM (1, 1) model of grey prediction is introduced to solve the problem. Based on the reliable data measured by many experiments, the authors predict the rest of the data that cannot be measured by experimental equipment by mathematical calculation, and then expands the sample data of a small amount of data measured by experiments [2] to improve the accuracy of data processing. In this paper, the experimental teaching instrument of GD-1 photoelectric effect tester is taken as an example to explain…”

In the Planck teaching experiment of photoelectric effect measurement, Due to the limitation of experimental equipment, only a few wavelengths of data can be measured, and the current data processing methods used in experimental teaching are not suitable for the situation of small data capacity, which leads to large errors in experimental results. In this paper, a data processing method of Planck constant based on grey prediction model is proposed, which can effectively improve the measurement accuracy of experiments.
