Light Reflection and Refraction Notes Reflection of Light:- The phenomenon of bouncing back of a ray of light after striking on a highly polished surface is called reflection of light. Laws of Reflection:- First law:- The angle of incidence is equal to the angle of reflection. i.e., ∠i = ∠r Second Law:- The incident ray, […]
