#: At any point on a surface we can find a normal direction which is at right angles to the surface, for the sphere these are the lines radiating out from the center of the sphere.

At ground level this decreases to about 1120-1000 watts / m < sup > 2 </ sup >, and by energy fractions to 44 % visible light, 3 % ultraviolet ( with the Sun at the zenith, but less at other angles ), and the remainder infrared.

At certain rotation angles, the reflected light will be reduced or eliminated.

* At high angles of body roll, the swinging arms that are mounted with large bearings to " cross tubes " that run side to side across the chassis ; combined with the effects of all-independent soft springing and excellent damping, this keeps the road wheels in contact with the road surface and parallel to each other across the axles.

At shallower angles, the ladder may lose its grip on the ground.

At most angles the loop has a fairly flat reception pattern, but when it is aligned perpendicular to the station the signal in one side cancels the signal in the other, producing a sharp drop in reception known as the " null ".
