Answer 2

reflection is when light bounces off an object if the surface is smooth and shine , like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. this is called specular reflection.

law of reflection:-

the law of reflection states that when a ray of light reflects off a surface , the angle of incidence is equal to the angle of reflection .
