Question

Carbon-14 dating method is based on the fact that

• A. carbon-14 fraction is same in all objects
• B. carbon-14 is highly insoluble
• C. ratio of carbon-14 and carbon-12 is constant
• D. All of the above

Answer 1

Answer: (C)

ratio of carbon-14 and carbon-12 is constant

Answer 2

By carbon dating method
Age of wood $=\frac{2.303}{.693}\times T_{0.5} log\Bigg(\frac{N^0}{N}\Bigg)$
$\, \, \, \, \, \, \, \, \, \, \, \, \, \Bigg[\frac{Ratio of C^{14} / C^{12} in living wood}{Ratio of C^{14} / C^{12} in dead wood}\Bigg]$
Hence, it is based upon the ratio of $C^{14} and C^{12}$
