The rapid advancement of digital communication infrastructure has fundamentally transformed the way human societies access, share, and govern information. This paper explores the profound intersection of physics and jurisprudence by examining how the foundational principles of electromagnetism and optics enable modern internet and mobile technologies, and how these technologies, in turn, serve as the backbone of transparent democratic governance through the Right to Information (RTI) Act, 2005. By analyzing the electromagnetic spectrum, radio wave propagation, total internal reflection in fiber optic cables, and sensor physics, we reveal the scientific substratum that underpins every digital interaction. Concurrently, we examine how the RTI Act harnesses these technological marvels to guarantee citizens' constitutional right to access government-held information. The study concludes that physics is not merely a tool of technology but an enabler of democratic transparency.
