If you look at the light of the moon tonight, rememberthat the light rays(光线)leftthe moon 1.3 seconds before they reached you. The nearest star is so far awaythat the light which you can see from it tonight started to traveltowards you four years ago at a speed of nearly 2 million...
Light as Rays Imagining light as a ray makes it easy to describe, with great accuracy, three well-known phenomena: reflection, refraction and scattering. Let's take a second to discuss each one. In reflection, a light ray strikes a smooth surface, such as a mirror, and bounces off. A...
The solar mirror has contiguous rectangular reflectors, having a rigid frame of variable angle in relation to a fixed one. This supports joists formed by parallel beams with profiled sections curved to match the curvature of the mirror and in turn supporting the long sides of the reflectors. ...
"B" in turn acting as both a receiver and retransmitter of these rays of energy to another body, star or planet, which we will call "C." This "C" we will refer to as the distribution point to other worlds, suns and stars of this Universe or group to which our world belongs, it...
