Final answer:
The reflection of a vector on a plane can be calculated using the law of reflection.
Step-by-step explanation:
In physics, the reflection of a vector on a plane can be calculated using the law of reflection. According to this law, the incident angle (i) and the reflected angle (r) are equal. The angles are measured with respect to the surface of the plane.
For example, if a vector is incident on a flat mirror, the reflected vector will have the same magnitude but will be on the opposite side of the plane. This means that the reflected vector will have the same direction as the incident vector but will point in the opposite direction.
To calculate the reflection of a vector on a plane, you can find the perpendicular (w) and parallel (w) components of the vector with respect to the surface of the plane. These components can be calculated using certain formulas or mathematical operations depending on the given vector and the angle of incidence.
