Draw on the A4 sheet of paper the normal. The angle of incidence equals the angle of reflection, at a movement against an obstacle and a reflection or rebound there. The angle of incidence and angle of refraction are mathematically related to the index of refraction of each material through the law of refraction, also called Snell’s Law. Independent Variable: Angle of incidence Dependent Variable: Angle of reflection Controlled Variable: Mirror Method: 1. The angle of reflection is the angle between the reflected ray and the. So angle of reflection means this thing is it will be the angle of. Summary The angle of incidence is the angle between the incident ray and the normal. Unlike reflection, the angle of incidence is not equal to the angle of refraction. And I love interest I have in this thing is going to be the angle of incidence. If light is traveling in one material and then refracts in a second material, it will bend towards the normal if the index of refraction of the second material, n 2, is greater than the index of refraction of the first material, n 1 (the light travels slower in the second material) ( n 1 n 2) (B). The higher the index of refraction, the slower light travels in that medium. If the angle of incidence is bigger than this critical angle, the refracted ray will not emerge from the medium, but will be reflected back into the medium. The index of refraction of a material is equal to the speed of light in a vacuum, divided by the speed of light in the material. Materials have a property called the index of refraction, which is symbolized using the letter n. Shopping cart example of refraction (©2020 Let’s Talk Science).
