light is a kind of wave & when light hits a reflective object , that light bounces off that object ->  when light wave hits a reflective object, the light wave bounces off that object  when light wave hits a reflective object, the light wave bounces off that object & reflection is when a wave bounces off a surface and travels in the opposite direction relative to the angle of incidence ->  when light wave hits a reflective object, the light wave is reflected  when light wave hits a reflective object, the light wave is reflected & a mirror is a kind of reflective object -> when light wave hits a mirror, the light wave will be reflected
