REFLECTION. Reflection of Light: The phenomenon of bouncing back of light into the same medium by the smooth surface is called reflection. Incident light: Light which falls on the surface is called incident light.
→ Speed of light is maximum in vaccum. Its value is 3 × 10 8 ms-1. → When light falls on a surface, following may happen: (i) Reflection (ii) Refraction (iii) Absorption Reflection → Bouncing back of light when it strikes on a polished surface like mirror. Laws of Reflection (i) Angle of incidence is equal to the angle of reflection.
