Light beams are reflected from surfaces according to the law of reflection, which states that the angle of incidence is equal...
You might wonder why the angles of incidence and reflection are measured between the rays and the normal line, and if you don...
The law of reflection is usually illustrated in science textbooks with flat or plane mirrors. You should be aware, however...
This episode starts from the phenomenon of refraction and moves on to Snell’s law.
