Explain the application of carbon-14 in carbon dating. 

Explain the application of carbon-14 in carbon dating.

• Carbon-14 isotope is radioactive with half-life t_½ = 5600years
• It is absorbed and maintained at constant concentration by plants during photosynthesis.
• When plants die carbon- 14 decays and its concentration falls due to lack of renewal by photosynthesis.
• If N₀ is the activity of fresh plant and N is the activity of dead plant after time t, the age of the dead plant t is deduced from
