UP Board Class 10 Science Book – Light: Reflection and Refraction
The chapter “Light – Reflection and Refraction” in the UP Board Class 10 Science Book explains how light behaves when it strikes mirrors or passes through lenses. Students learn about laws of reflection, plane and spherical mirrors, and how images are formed.
It also introduces refraction, the bending of light as it moves between different mediums, and discusses lens types, focal length, and real and virtual images.
Through ray diagrams and numerical problems, students develop a strong conceptual understanding of optical phenomena — essential for board exams and higher studies in physics. This chapter builds the foundation for topics like human eye and optical instruments.
