This document discusses reflection of light. It describes two types of reflection: regular reflection, which occurs on smooth surfaces like mirrors and reflects light regularly; and diffuse reflection, which occurs on rough surfaces and reflects light irregularly in different directions. The document also lists activities that involve identifying materials that reflect light and demonstrating the path of light rays using a medium like dust or smoke.

Reflection

13. Regular Reflection

14. When light falls on a mirror, steel plate,
smooth floor tile etc, it is reflected
regularly. This is known as regular
reflection.
Mirrors are surfaces which reflect light
regularly

15. Rough Surface
Rays reflected at different
directions
Diffuse
Reflection

16. Diffuse Reflection

17. When light falls on rough
surfaces, it is reflected
irregularly. This is diffuse
