বিষয়ে Ytterbium
Ytterbium is a soft, malleable rare earth element that slowly oxidizes in air. Ytterbium atomic clocks are even more precise than cesium clocks.
Uses & Applications
Atomic clocks, stress gauges, metallurgical additive, fiber optic amplifiers, and dental porcelain.
মজা কথা
Ytterbium atomic clocks are so precise they could detect gravitational time dilation from raising the clock just one centimeter.
