GENERAL KNOWLEDGE

Detailed explanation-1: -The carbon-14 method was developed by the American physicist Willard F. Libby about 1946. It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50, 000 years old.

Detailed explanation-2: -Dating games When the plant or animal dies, they stop absorbing, but the radioactive carbon that they’ve accumulated continues to decay. Measuring the amount left over gives an estimate as to how long something has been dead.

Detailed explanation-3: -Archaeologists have two main ways to tell the age of sites and artifacts. Relative dating tells how old something is in relation to other objects, but cannot provide a year or specific date of use. In contrast, absolute dating provides a specific calendar year for the occupation of a site.

Detailed explanation-4: -Accelerator mass spectrometry (AMS) is a modern radiocarbon dating method that is considered to be the more efficient way to measure radiocarbon content of a sample. In this method, the carbon 14 content is directly measured relative to the carbon 12 and carbon 13 present.
