heya mate please say important topics of light reflection and refraction i will be mark as brainliest answer i give u to 50 points​

Answer 1

Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection. Diffuse reflection is when light hits an object and reflects in lots of different directions.
