or reflected by the sensing object, it changes the amount of light that arrives at the receiver. the receiver detects this change and converts it to an electrical output. the light source for the majority of photoelectric sensors is infrared or visible light (generally red, or green/blue for identifying...
resistant to attack by acids and stable in air, though flammable when heated, and it is one of five elements with the unusual property of expanding in volume when solidified ( silicon , germanium , gallium , and bismuth being the other four). when molten antimony is allowed to cool, its surface gains...
the new element within this oxide was therefore called yttrium, and today is one of four elements named for the village of ytterby, the others being terbium , erbium , and ytterbium . yttrium is a fairly common rare earth element and serves an extremely broad range of functions. one of the most widely...
dense element that is solid at room temperature (behind lithium ), and it is one of only three elements (with sodium and lithium) capable of floating on hydrocarbon-based mineral oil. though potassium is nontoxic, it is classified as a hazardous material because of its dangerous reaction with water....
