In other words, if a source is emitting radiation in all directions (i.e., in a 4π steradian), the detector will never be able to see more than half of that radiation, or have 50% efficiency.

WebbIn some applications, the direction of motor rotation is critical to maintaining high-level performance and ensuring the safety of the load. This holds particularly true for devices such as pumps and cooling fans, which have angle blades. Rotating such machinery in the wrong direction leads to poor performance and eventually catastrophic failure.

WebbThe case of improper rotations in two dimensions is more interesting. In the previous class handout cited above, we noted that the most general improper rotation matrix in two-dimensions is of the form, R(θ) = cosθ sinθ sinθ −cosθ , where 0 ≤ θ < 2π, (7) which can be expressed as the product of a proper rotation and a reﬂection, R = Webbrate of change is 2πL /T.
