The normal ray is the outward-pointing ray perpendicular to the surface of an optical medium at a given point. In reflection of light, the angle of incidence and the angle of reflection are respectively the angle between the normal and the incident ray (on the plane of incidence) and the angle between the normal and the reflected ray.

Web3 de ago. de 2014 · Now, in general, if we know two side lengths of a triangle (call them x and y) and the angle measure between them (call it θ ), then the area of the triangle is given by A = 1 2 x y sin ( θ). Applying this to our scenario, since the angle between the two given sides can vary, then so too can the area of the triangle.
