WebFeb 28, 2024 · Thus, if the incident wave lies in the X-Z plane, then so do the other two waves. In other words, the incident, reflected, and transmitted waves all lie in one single plane. This is the first law of reflection. Secondly, sin θᵢ = sin θᵣ and thus, θᵢ = θᵣ. That is, the angle of incidence is the same as the angle of reflection. Webhow an electromagnetic wave can be produced by an oscillating (and hence accelerating) charge. Finally, in Section 8.8 we discuss the re°ection and transmission that occurs when ...
