If the reflecting surface is very smooth, the reflection of light that occurs is called specular or regular reflection. The laws of reflection are as follows:
# มุมตกกระทบเท่ากับมุมสะท้อน
#The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane.
#The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal.
