what do you think you know about physics, physics is the study of matter under the effect of energy, but does this includes solid states bodies, atoms at ground states, object at microscopic size or object moving faster than light? these and more is what prompt me to ask again what is physics?
the law of reflection of light state that the
incident ray, the reflected ray and the normal all lie at the same point at the
point of incidence, the angle of incidence is equal to the angle of reflection.
