Class 10 Science Chapter 9 Notes
Light plays an important role in our daily life by helping us see objects around us. This chapter helps students understand how images are formed by mirrors and lenses and how light changes direction when it travels from one medium to another. A clear understanding of these concepts is essential for solving numerical problems and performing well in board examinations.
