The angle of incidence refers to the angle at which a wave hits a surface or boundary. It is measured between the incoming wave and the normal line, which is perpendicular to the surface.
2.The angle of incidence determines how waves will reflect, refract, or diffract when they encounter a boundary. The greater the angle of incidence, the greater the change in direction of the wave.
3.The law of reflection states that the angle of incidence is equal to the angle of reflection when a wave bounces off a surface. This means that the angle of incidence determines the angle at which the reflected wave will travel.
4.The angle of incidence affects the amount of energy transferred by a wave because it determines the direction and intensity of the reflected or refracted wave. The greater the angle of incidence, the more energy will be transferred in a different direction.
5.The angle of incidence is directly related to the index of refraction, which is a measure of how much a material can bend light waves. As the angle of incidence increases, the index of refraction also increases, causing the wave to bend more when it crosses a boundary between materials.
