The formula for calculating reflection angle in a 2D plane is: θr = θi - 2θn, where θr is the reflection angle, θi is the incident angle, and θn is the normal angle.
The incident angle in a 2D plane can be determined by drawing a line from the point of incidence to the point of contact on the reflecting surface. The angle between this line and the normal line (perpendicular to the reflecting surface) is the incident angle.
No, the reflection angle cannot be greater than the incident angle in a 2D plane. The reflection angle is always equal to the incident angle minus twice the normal angle. Since the normal angle cannot be negative, the reflection angle cannot be greater than the incident angle.
The reflection angle will also change when the angle of incidence is changed. As the angle of incidence increases, the reflection angle will also increase. Similarly, as the angle of incidence decreases, the reflection angle will also decrease. This relationship is described by the formula θr = θi - 2θn.
