China Wholesale Ellipsometer Pricelist – LCP-18 Apparatus for Measuring Speed of Light – Labor
China Wholesale Ellipsometer Pricelist – LCP-18 Apparatus for Measuring Speed of Light – Labor Detail:
Since Galileo first tried to measure the speed of light in the 16th century, people have used the most advanced technology to measure the speed of light in various periods. Now, the distance that light travels in a certain time has become the unit standard of all length measurement, that is, “the length of meter is equal to the distance that light travels in 1 / 299792458 second interval in vacuum.” the speed of light has also been directly used in distance measurement, The speed of light is closely related to astronomy. The speed of light is also an important basic constant in physics. Many other constants are related to it, such as Rydberg constant in spectroscopy, the relationship between vacuum permeability and vacuum conductivity in electronics, the first radiation constant and the second radiation constant in Planck’s blackbody radiation formula, The mass constants of protons, neutrons, electrons and muons are all related to the speed of light C.
Optional experiments: Measure the refractive index of various media such as organic glass, synthetic quartz, and liquid by using an optional media tube.
