Reflection and Refraction — Tech Evolutions

Entry	Year	Description	Impact
N/A	N/A	The principles of reflection and refraction are fundamental laws of physics, established through scientific observation and experimentation. They are not subject to 'amendments' in the legislative or constitutional sense. Scientific understanding evolves through new discoveries and refinements of theories, but the core laws of reflection and refraction remain constant.	This highlights that while the UPSC syllabus includes diverse topics, the nature of 'amendments' is specific to certain domains (e.g., Constitution, laws). For physics, focus on the evolution of theories and technological advancements rather than legal amendments.
